back to contents Primer 9.3 RC1 Miscellaneous enhancements –Copy/translate –Cut section display –Include file control from Edit panels –Overspill from text boxes –INCLUDE file version control –Check for discontinuous rigid bodies –New options in Write –Other Spotwelding Bolts Mechanisms and seat positioning Dummy positioning Seat foam compression Instrument Panel Impactor positioning Automatic assembly enhancements
back to contents Copy & translate (Also available for Rotate)
back to contents Cut Sections Section through shells shows true thickness The capability and menu is very similar to D3PLOT 9.2. Start the cut section menu (or shortcut X). Pick a node to create the section – shortcut N. Dragging the section – shortcut D. Change display of elements on +ve and –ve sides of the plane Orientation of cutting plane
back to contents INCL file location Edit panels now state which INCLUDE file the entity is in. Can change INCL file using the browse button. Option to Find Referenced Items. If INCLUDE is Transformed, (T) appears here. In this case the numbering shown will be the transformed numbering, not the numbering in the keyword file.
back to contents Text boxes Where the text is too long to fit in a text box, this is now indicated by white horizontal bars: For some text box types, the whole text can be seen by hovering over the text box with the mouse. This will be extended to all text boxes in future releases.
back to contents INCLUDE file – Version control How can we tell that a model contains up-to-date INCLUDE files? Create “Versions” (e.g. each Version may correspond to a Design Gateway) by right-click of the Model in the Include Menu. Set the Version against which INCLUDE files should be checked.
back to contents INCLUDE file – Version control Identify an INCLUDE file as belonging to a Version (or design gateway) as shown. This information is then kept in the keyword file. The model check will then identify any INCLUDE files that belong to a different version (or design gateway) than the default version for the model.
back to contents Check for discontinuous rigid bodies New check (warning) – rigid body with discontinuous mesh. This check is optional – activate it using Preferences: –Primer=>Checking=>Model quality checks=>Rigid=>Rigid body continuity check.
back to contents New options in Write When writing a model using “Select Include files”, the default is for all selected INCLUDE files to be written to a sub- directory. New button RENAME/INC changes the destination of all the selected INCLUDE files to RENAME. This setting overwrites the original INCLUDE file…
back to contents New options in Write Press RENAME/INC again, this automatically renames the selected INCLUDE files by adding _1, _2 etc to the file name.
back to contents Miscellaneous Enhanced input translator for RADIOSS Block format: –Complex definitions of sets now supported. –More material types translated. –Engine file translated as well as Starter file. –For further details, please contact us. Bill of Materials: if “calculate mass” option is set, Primer now writes the centre of gravity XYZ coordinates as well as the part mass. Orient Scale and Rotate: option to centre the transformation on the Part Centre of Gravity. Applies only if a single part is selected.
back to contents Spotwelds Spotweld capabilities are now found under Tools=>Connection. The same menu is used to create or modify several connection types (spotwelds, bolts). Primer 9.2 Primer 9.3
back to contents Primer 9.2 relied on *ELEMENT_BEAM_PID for many of the spotwelding functions. Primer 9.3 works differently – connection data is stored separately from the FE data: –Failed welds are retained in the model, can be fixed any time. –When creating from a spotweld file, the original XYZ coords are retained. –Easy to change the welds, e.g. beam-to-solid. –Can read and work with spotwelds that were defined outside Primer, e.g. solid spotwelds, beam spotwelds without *ELEMENT_BEAM_PID, etc. Connection data created automatically on entering the spotweld menu. Other connection types: bolts etc. Spotwelds Weld file Spotwelds LS-DYNA model Primer 9.2: Weld file Spotwelds LS-DYNA model Primer 9.3: Bolts, etc Connections
back to contents Spotwelds Connection entities may be displayed separately from their FE data. They are coloured by status: green=realized, red=failed, etc.
back to contents Solid spotwelds All Primer 9.2 capabilities for beam spotwelds are available in Primer 9.3 for beam and solid spotwelds. When creating spotwelds (or reading a spotweld file), Primer 9.3 offers the choice of beam, hexa, 4 hexas, etc. *DEFINE_HEX_SPOTWELD_ASSEMBLY is created automatically in the case of multiple-hexa spotwelds.
back to contents Connections Table In Primer 9.3, spotwelds are modified, repositioned, reprojected, etc, using the Connections Table
back to contents Connections Table To start the table, select which connections to display, then press Apply. Choose which spotwelds to display in the table – e.g. those attached to certain panels, or in this case by selecting the connection entities Using FILTER, you can then select connections of a certain type or status (e.g. welds that failed to create)
back to contents Connections Table Sort by clicking on the column headers, e.g. to group all the bad welds together
back to contents Connections Table Control which columns are visible in the Table using View. Hover-text is available
back to contents Connections Table Click on a weld to select Multiple-select by click and shift- click or CTRL-click Use this drop-down to decide what action should be taken for the selected welds when you press Apply
back to contents Connections Table Changing from beam to solid spotwelds: –First, if the model does not already contain a Part that is valid for solid spotwelds, create one. –Select the spotwelds in the Table. –Right-click on Subtype for the selected welds, click Solid (or 4 solids etc). –Also right-click on Part ID, select the new Part (or if the model contains only one valid part for solid spotwelds, Primer will choose it automatically). –Check that the Action box is set to “update & remake”. –Press Apply Selected. –The selected welds will be re-created with solid elements.
back to contents Connections Table Repositioning a spotweld: –1 - Select the weld (or several welds) into the connection table –2 - Right-click on the coordinates, choose “Pick (from shell)”. 4 –4 - Ensure the Action is set to “update & remake”, press “Apply selected”. + 3 –3 - Click on the new position.
back to contents Reading spotwelds from File These file formats are the same as for Primer 9.2. Additional information is needed to create the spotwelds, e.g. what type of element should be used. The files can be written by Primer, by CAD packages or other programs, or csv- format from a spreadsheet. “Primer connection file” is a new file format that contains more information. This file is created only by writing out from Primer.
back to contents As the spotwelds are read from the file, connection data is created. Spotweld elements are created for error-free welds. Any welds with errors will have connection data with status “bad”, but no spotweld elements. The bad welds are automatically presented in the Connection Table. We recommend to add the columns “Error” and “Details” to see why the welds could not be created. The table can be used for fixing the welds, using the sorting, multiple- selection, right-click to change data, and “remake” facilities. Reading spotwelds from File
back to contents Spotwelding Panels sometimes consist of more than one CAE Part. Spotweld files written by the CAD system refer to parts by CAD name or number, not CAE part ID. From the spotweld file, we do not know which CAE Part should be connected. In Primer 9.3, each panel (“layer”) in the spotweld may be defined by: –One or more CAE Part ID. –One or more CAD part name. –Primer assemblies. –Part sets. CAD Part = APP_FRAME_12345 PID PID PID Example: Taylor-welded blank Spotweld files can refer to CAD part name instead of CAE Part ID. Use the Bill of Materials (spreadsheet) to tell Primer the CAD name for each part.
back to contents Spotwelding Various methods are available in the Connections Table to define which part(s) may be connected by each spotweld: “More” allows different Parts to be selected For example, change definition to “Multiple Parts” and add more possible parts to the list. The spotweld will connect to any one of the listed parts
back to contents Spotwelding Various methods are available in the Connections Table to define which part(s) may be connected by each spotweld: “Change to” changes the selection method but keeps the same Part(s) CAD names are available only if these have been read in via Bill of Materials
back to contents Spotwelding Spotweld panels now defined by CAD Name:
back to contents Using CAD names for parts Read in a spreadsheet (csv format) using BOM. Example Bill of Materials with CAD part names: CAE Part ID CAD Part Name or number
back to contents Bolt connections The connection positions can be seen; the connection properties may be created or edited Bolt-type connections can be “realized” as rigid patches or nodal rigid bodies
back to contents Bolt connections Manual creation of bolts through Tools=>Connections=>Create: Bolt selection button
back to contents Bolt connections Manual creation of bolts through Tools=>Connections=>Create: –Selection of shells/parts to connect. –Bolt creation method: X, Y, Z coords – type in coordinate of bolt. Pick screen point – click on the screen to create bolt. Pick connection – pick an existing Primer connection point. Pick single node – pick an existing node as the position of the bolt. Between nodes – pick two existing nodes, the bolt will be created between the nodes. Useful for creating bolts over holes.
back to contents Bolt connections Manual creation of bolts through Tools=>Connections=>Create: –Options for bolt creation. –Data for creating bolts: Optional matl id for bolts – If creating a rigid body merge connection, you can specify the rigid material used here. For the default setting (automatic), Primer creates a rigid material for the bolt. Rigid bolt type – Two bolt types available, Merge or NRB (nodal rigid body). Bolt diameter – The diameter of the bolt(s) you are creating.
back to contents Bolt connections Types of bolt: –NRB’s (Nodal Rigid Bodies) Nodal rigid bodies are created at the connection point to the diameter specified. –Rigid Merges Rigid patches are created at the connection point to the diameter specified, and jointed by a rigid body merge.
back to contents Bolt connections Creation of bolts from existing connection points/spotwelds: –If you already have connection points/spotwelds in the model, these can easily be converted to rigid bolt connections using the connections table.
back to contents Bolt connections Creation of bolts from existing connection points/spotwelds: –Select the connections you wish to convert to rigid bolts: Selections in the connections table can be made by using the left mouse button and the “shift” and “ctrl” keys.
back to contents Bolt connections Creation of bolts from existing connection points/spotwelds: –The type of the connection can be changed for the selected connections: By right clicking over the selected connections, under the “Type” column, the “Rigid” type can be selected.
back to contents Bolt connections Creation of bolts from existing connection points/spotwelds: –Once “RIGID” is chosen for the type, the subtype can be chosen: By right clicking over the selected connections, under the “Subtype” column, the “Merge” or “NRB” bolt types can be selected.
back to contents Bolt connections Creation of bolts from existing connection points/spotwelds: –After the “Type” and “Subtype” is set, the connections can be remade: By clicking “Apply selected” the modified connections will be remade as rigid bolts. Make sure “update & remake” is selected as the action.
back to contents Bolt connections Automatic creation of connection points from constraint FE data: –Primer can convert rigid merges and NRB’s to connection points. These connection points can then be manipulated as a standard connection definition (i.e. converted to another type (eg. spotwelds), written out to a spotweld file etc.).
back to contents Bolt connections Automatic creation of connection points from constraint FE data: –Various options are available when creating connection points from constraint FE data: The maximum size of the constraint selected can be set here The type of constraint selected can be chosen here For “Selection mode”, if “constraint” is chosen a list of all the rigid constraints of the selected type (NRB or merge) appears at the bottom. You select the constraint(s) you wish to convert to a connection definition here
back to contents If “attached to part” is selected for the selection mode, constraints can be selected by the parts they connect. A part selection list is available at the bottom of the panel Bolt connections Automatic creation of connection points from constraint FE data: –Various options are available when creating connection points from constraint FE data: The constraints can be selected if they are attached to any part selected, or if all the parts they are attached to are selected
back to contents Mechanisms Determinate: 1 DoF Indeterminate: >1 DoF Primer 9.3 has a new capability to position mechanisms. Similar to dummy positioning, but not limited to tree-like systems. Mechanism can be determinate or indeterminate, and is not limited in terms of number of links or complexity. Tree: No. DoF = No. of joints
back to contents Mechanism definition Assemblies identified by Parts or Part Sets, e.g. back, squab, front links, etc. During positioning, each assembly will behave as if rigid. Connections (joints) defined at nodes. These are used purely for positioning the mechanism and are independent of any LS-DYNA joints. Connection types: pin, hinge, sliding. Reference Points (e.g. H-Point) – mechanism can be positioned by specifying coordinates of reference points. Assembly Hinge joint Assembly Sliding joint
back to contents Mechanism definition Use the new “Mechanism” menu to create or modify the mechanism definition (assemblies, connections and reference points). To save the mechanism definition, press UPDATE_MECH. The mechanism definition is kept in the Keyword file after *END (similar to the Dummy tree file).
back to contents Mechanism definition - Assemblies Define Assemblies using Parts or Part Sets
back to contents Mechanism definition - Connections Which assemblies are joined? Nodes to locate joint position and axis. The nodes must be attached to one of the connected assemblies.
back to contents Mechanism definition - Points To which assembly is the point attached? Location of point using initial XYZ coordinates, or an existing node
back to contents Positioning the mechanism To start positioning the mechanism, use “Position” button. First, use “Drag Assemblies” menu to restrain any assemblies that should not move. The restraints can be altered at any time during positioning. X-translation Y-translation Z-translation X-rotation Y-rotation Z-rotation
back to contents Next, use “Connection list” to lock any joints that should not be free during positioning. The connection status can be changed at any time during positioning. Positioning the mechanism
back to contents The mechanism can be dragged at any time while in the Position menu – the assemblies will be displayed in grey during dragging. Any restraints, and the joint status (locked/free), will be respected. Positioning the mechanism
back to contents Positioning the mechanism The angular position of any assembly can be altered using the “Rotate Angles” menu.
back to contents H-point X1, Y1, Z1 H-point X2, Y2, Z2 Positioning the mechanism The mechanism can be positioned by typing new coordinates (or displacement) for a reference point. In this context, * is used to leave a coordinate or displacement component unprescribed (free). In this menu, reference points may also be restrained, and new points may be created.
back to contents Positioning the mechanism When you press “Accept”, the coordinates of all the newly positioned nodes will be saved in the model. If you press “Reject”, or dismiss the Position menu, or write out the model without pressing “Accept”, the coordinates will be reset to their previous value. Positions may be saved, then retrieved later. These saved positions are also written to the keyword file, so will be available next time you read in the model.
back to contents Saving/retrieving positions Save a new position, or overwrite an existing one Give title, “Save it” Retrieving a previously saved position
back to contents Application to dummies A dummy is also a mechanism. Typically it is under-constrained – several different configurations are possible for any given position of hand, foot, etc. We may want to restrain different parts of the dummy; then it may become determinate, or over- constrained. Primer can use the dummy’s tree file to enable the dummy to be treated like a mechanism – no additional data is required from the user.
back to contents Dummy definition Assemblies identified by Parts or Part Sets, e.g. torso, head, limbs, etc. During positioning, each assembly will behave as if rigid. Connections (joints) automatically defined from the dummy model. No modification is allowed. Reference Points The H-Point is automatically available as a Reference Point; others may be created. Assembly Hinge joint Assembly
back to contents Dummy Tree File Create/Modify After reading in a dummy key file, use Tools=>Occupant=>Dummies=>Modify to modify the dummy tree file definition. A new tree file can be created from the Create menu. Unlike the Modify Mechanism menu, there is no connections menu; joints are defined in the tree file as a property of Assemblies. To save the dummy definition, press UPDATE_DUMM. The dummy tree file definition is kept in the Keyword file after *END.
back to contents Positioning the dummy To start positioning the dummy, use “Position” button. The “Rotate angles” menu is the same as in Primer 9.2 – it shows the angle of each assembly to its local axis. Type in new angles, or drag using left, middle or right mouse buttons (for rotations about local X, Y or Z axes respectively).
back to contents Positioning the dummy To use the new “mechanism” capability, switch to Drag Assembly. Primer generates the necessary data automatically using the dummy’s tree file. The “Drag assembly” menu offers translational and rotational restraints for each assembly.
back to contents Restraining the dummy After positioning hands onto steering wheel and foot onto footrest, these can be restrained ready for re-positioning of the H-point.
back to contents Restraining the dummy Drag torso into new position (you will need to release X and Z restraints on the torso):
back to contents Limits on drag motion Drag is limited by the stop-angles existing in the dummy model. Drag is also limited by the available degrees of freedom at each joint.
back to contents Limits on drag motion Some movements of the dummy are not possible, due to the limited degrees of freedom at some joints. If the hands are fully restrained, it may not be possible to drag the torso freely in some directions because this would pull the wrists apart. This “locking” effect is less pronounced when the elbows are raised.
back to contents Positioning the dummy The dummy has its H point already set in its model. In this menu, reference points may be restrained, and new points may be created. It can be useful to create reference points on the hands, knees, nose, etc so the dummy position can be matched to measured data.
back to contents Saving/Retrieving positions The mechanism can be positioned by typing new coordinates (or displacement) for a reference point. Reference points may also be restrained, and created in this menu. The saved positions are written to the keyword file ready for re-use later.
back to contents Saving/Retrieving positions Dummy Angles File – external file for transferring dummy position across models, or as a way of saving positions that can be used with successive versions of similar dummies.
back to contents Saving dummy position When you “Accept” the positioning of the dummy, Primer will find that some nodal pairs at joints are no longer exactly coincident. Check the nodal separation; if small, select AUTOFIX to make the joint nodes coincident. This results in slight geometry change to the model.
back to contents Combined mechanisms One mechanism may be linked to another, e.g. seat squab to dummy pelvis. Then the dummy and seat can be dragged together in a single action. To do this, use “children” on the mechanism menu.
back to contents Combined mechanisms When defining the dummy as the child, you need to select the assemblies in the dummy to be slaved to the master mechanism. Select all three translational degrees of freedom to be linked. The rotations are not coupled. c
back to contents Combined mechanisms When positioning the combined mechanism, the dummy’s assemblies appear in the seat mechanism menu automatically. Moving the seat moves the dummy, but not vice-versa: the coupling is one-way. Save/Retrieve will include the combined dummy/seat position. Seat Dummy
back to contents Mechanisms/Dummies – Command File Mechanisms and dummies may now be positioned using command- line (for example, in a command file as part of a batch process). Example: /READ DK seat_model.key /MECHANISM ASSEMBLY 6 FIX DONE POINT H-Point POSITION DONE ACCEPT /WRITE DK new_model1.key /MECH POINT H-Point POSITION DONE ACCEPT /WRITE DK new_model2.key New command MECHANISM Can restrain, translate or rotate assemblies. If the correct restraints were already saved in the keyword file, there is no need to add commands here to restrain the assemblies. Can restrain, translate or type new coordinates for (“Position”) Reference Points. This command file writes two models, each with the H-point in a different position.
back to contents To find the available commands, type “H” (for “Help”) in the dialog box. Type one of the options shown in the menu. Type “H” again… etc. The same commands that can be typed in the dialog box, will also work when used in a command file. Mechanisms/Dummies – Command File
back to contents Seat foam compression Dummy has been positioned, penetrating the foam. “Primer” and “Dyna” methods are available to deform the foam under the dummy. “Primer method”: –Automatically move dummy out of seat until there are no penetrations. –Automatically move dummy back to its starting position, while using contact depenetration to prevent the top surface of the foam from penetrating the dummy. –At the same time, interior nodes within the foam will be displaced to attempt to distribute the strain uniformly through the foam.
back to contents Seat foam compression “Dyna method” - foam is compressed by LS-DYNA analysis: –Automatically move dummy out of seat until there are no penetrations. –Automatically rigidify dummy and the seat frame, create boundary condition for an LS-DYNA analysis that will move the dummy back to its starting position. –User checks and writes out the model, runs LS-DYNA. –Once analysed, the deformed seat geometry and initial stresses can be read back into the original model.
back to contents Seat foam compression Seat squash – activated through Tools=>Occupant=>Seatsquash. The “Squash” button is used to setup either the simple Primer seat-squash or a LS-Dyna analysis seat-squash
back to contents Seat foam compression Seat squash – Simple squash using Primer – Process: You will get a message about saving your model before carrying out the seat-squash You will get a message about moving your dummy to the H-point position Select the top surface of the seat (eg. Null shells) Select the bottom surface of the seat Select the deformable foam parts of the seat Select or create the contact between the dummy and the seat Select the components that make up the dummy Select dummy movement increments (see next slide)
back to contents Seat foam compression Seat squash – Simple squash using Primer – Process: –Increments must be chosen for the distance you want the dummy to move for each iteration during the de-penetration process. –A value of solid element relative volume can be input to stop the seat squash should a solid element become too deformed. –Clicking “Next” after these values are set will activate the simple seat-squash. The dummy will move away from the seat until de-penetrated, and then return to its original position, squashing the seat.
back to contents Seat foam compression Seat squash – Setting up a LS-Dyna seat-squash analysis – Process: You will get a message about saving your model before carrying out the seat-squash You will get a message about moving your dummy to the H-point position Select the parts you wish to keep deformable in the seat Select the components that make up the dummy Select all the components that make up the seat Delete redundant contacts in the model Select or create the contact between the dummy and the seat Select dummy movement increments (see next slide)
back to contents Seat foam compression Seat squash – Setting up a LS-Dyna seat-squash analysis – Process –Increments must be chosen for the distance you want the dummy to move for each iteration during the de-penetration process. –After clicking “Next” various LS-Dyna inputs can also be modified. –Clicking “Next” after these values are set will activate the simple seat-squash. The dummy will move away from the seat until de-penetrated. The seat-squash LS-Dyna model will then be prepared for writing out and running.
back to contents Seat foam compression Seat squash – Import/Export of reference geometry: –After running a LS-Dyna seat-squash analysis, a dynain file will be created. This will contain the updated nodal positions and initial stresses of the elements. When importing the dynain file, you get the choice of which data you want to read in. This means that after running an LS-Dyna seat-squash analysis you can read the updated geometry and stress information for the deformed seat into your original model. –Dynain files can also be exported from this panel - useful for saving seat data before carrying out simple seat-squashes.
back to contents Instrument Panel Pendulum Impact New feature – setup of multiple IPP impact models for ECER21. Both interactive and batch mode supported. Easy creation/modification of target points. Automated positioning and de- penetration. True and realigned approach angle supported. Data saved in model or written to csv target file.
back to contents The IP Pendulum Impactor model Use Arup-supplied pendulum model. Model includes hinged base and rigid extendable stick. Uses VELOCITY_GENERATION for correct initial angular velocity. Post *END keywords store contact info, H-point coords, impact velocities, target points. Impactor read in as separate include file. Written as INCLUDE or INCLUDE_TRANSFORM for realigned approach angle case.
back to contents IPP: Accessing the function IPP master menu is accessed through Occupant popup of the Primer tools menu.
back to contents Sets up main IPP parameters. These are read from post *END data if available. Easy creation of pendulum to IP contact. Standard and reduced impact velocity (airbag). Base and forward H-point coords. Mode for true or realigned approach angle. Accesses the targeting panel. IPP: master menu
back to contents IPP: Targeting panel - functionality Displays existing targets in model. Read in csv file to load new points. Pick node as target point and add to list. Modify existing target coords or pick new node. Add multiple target points with “select nodes” function.
back to contents IPP: Targeting panel Initial appearance of panel before targeting: –Light blue background: Misaligned with trim normal, probably cannot be contacted by pendulum. –Red background: Out of range – definitely cannot be reached by the pendulum. –Dark blue background: not yet positioned. –“uncontactable points” allows removal at users discretion.
back to contents IPP: Targeting panel - positioning Position function will position and de-penetrate at selected (blue) targets. Successfully positioned set to green, failed to red. Green points may be instantly repositioned. Red points will not be attempted again unless “reset failed”.
back to contents IPP: Current target point information Master menu displays detailed positioning info for current target point. Target point coord. with sketch. Contact point coord. with sketch. Trim normal to approach gross angle. Alpha, beta, theta angles. Line of flight unit vector. Velocity at centre of pendulum.
back to contents IPP Targeting panel: Saving targets List of targets can be stored in model. Or written to a csv targeting file ready for batch processing. Full data may be exported to a csv info file. To write models switch from setup panel to keyout panel.
back to contents IPP: Writing out the models Top level output directory for all sub- directories. Default sub-dir and file names can be modified by user. Illegitimate (red) targets greyed out. Select targets and Apply Keyout. _F signifies forward H-point. _R signifies re-aligned mode.
back to contents IPP: Configuring csv file for Setup panel Model is loaded in Primer, contact, H-point and alignment mode are set in master menu. Minimum target info input required is: nx, ny, nz are user defined values of trim normal vector at target point and (if non-zero) override calculated normal. The 3 mode flags, ignored in this mode as master menu panel sets the modes, should be set to zero
back to contents IPP Batch mode Command line syntax for running IPP build and keyout in batch mode is: BUILD READ. In this case full info is required for the csv file: h_flag, r_flag specify the H-point and approach mode (true/aligned) 0 = nominal condition, 1 = alternative value, 2 = both loadcases v_flag specifies the velocity 0 = nominal condition, 1 = reduced value
back to contents Automatic Assembly (Database/Template) Improvements to the Database/Template system for automatic assembly of models from INCLUDE files: –INCLUDE files can be in NASTRAN format; this allows the Crash CAE team to share data for assembly with the NVH CAE team. –Connection files can be included in the database. The connections (spotwelds, bolts, etc) will be created during model build. –Version control: several different versions of each component may be included in the database. The user can then select the desired version when building a model.
back to contents Connections in Model Assembly Unconnected parts Assembled, connected and checked model Primer’s Database/Template system of model assembly has been extended to accept connection files. This method allows connections to be created during model assembly. Primer Connections file: - Spotwelds - Bolts - Other types…
