2. Overview Of SAGE CRISP n SAGE CRISP is a purpose-written Geo- technical, Finite Element Analysis package n CRISP (the FE Analysis engine) has been used successfully by universities and companies for over 20 years n Nearly 100 academic papers have been published using CRISP

3. Overview Of SAGE CRISP *Pre-Processor *FE Analysis Program *Post-Processor *Report Generator *Help on the GUI *Help on FE errors n SAGE Engineering have added a new user- friendly Graphical User Interface operating under Microsoft Windows 95 and Windows NT. n The SAGE CRISP software suite comprises:

4. Graphical User Interface n CAD-style, graphical input window allows meshes to be quickly built and altered n Graphical selection of nodes, edges and elements n Full support for WYSIWYG printing and clipboard cut-and-paste operations

5. Graphical User Interface n Graphically apply displacement fixities to nodes and edges n Graphically apply total or excess pore water pressure fixities to nodes and edges n Graphically apply point or distributed loads to nodes and edges

6. Graphical User Interface n Graphically add and remove elements to and from the mesh to simulate construction or excavation activity n Graphical representation of each discrete stage of analysis; including the display of loads, fixities and construction sequences n Automatically generate unstructured or structured finite element meshes

7. Reporting n Report on selected input and output data using the SAGE CRISP Report Generator n Apply formatting to Reports in a standard spreadsheet environment n Store preferred formats as re-usable Templates that can be applied to any Report n Print Reports directly, or export the data for use in other applications

8. Analysis Types n Drained, Undrained and Fully Coupled (Biot) Consolidation analysis n Two dimensional analysis in Plane Strain or Axisymmetry n Three dimensional analysis (Note: 3D is only available without the graphic pre and post processors)

9. Constitutive Models n Cam-clay based models including *Original Cam clay (half ellipse) *Modified Cam clay (half circle) *Schofield model with no-tension cutoff limits *Three Surface Kinematic Hardening model

10. Elasto-plastic Models n Homogeneous, anisotropic, linear elastic n Non-homogeneous, anisotropic, linear elastic n Elastic-perfectly plastic with the following failure criteria: *Mohr-Coulomb *Drucker-Prager *Tresca *Von Mises

11. Structural elements n Beam, bar and slip (interface) elements

12. Parametric Analysis n Compare results from parametric analyses using the SAGE CRISP Post-Processor *Material Properties *Drainage Conditions *Construction Sequences *Applied Loads *Numerical Dependence *...and more n Run parametric studies to examine the effect of changing:

13. Building a Mesh n Create nodes and elements by drawing them directly onto the screen n Use the Automatic Mesh Generator to quickly and easily build complex finite element meshes from simple super meshes n Unstructured and Structured Automatic Mesh Generators

14. Unstructured Mesh Generation n Create a freeform Super Mesh containing Super Elements of any shape and with any number of sides n Finite Elements are generated according to grading parameters specified at nodes in the Super Mesh

17. Structured Mesh Generation n Create a Super Mesh of quadrilateral Super Elements n Finite elements are generated according to the pattern of divisions specified for each edge in the Super Mesh

20. Boundary Conditions n Fix nodes and edges against horizontal, vertical or rotational movement n Apply prescribed displacements n Drain nodes and edges to either atmosph- eric pressure, or to a static pressure head n Set total or excess pore water pressures n Graphical display of boundary conditions

22. Pore pressure fixities applied to top surface

23. Define Material Zones n Create ‘Zones’ representing homogeneous regions of soil n Choose constitutive models and define soil parameters for material zones via the Material Properties dialogue box n Coloured display of material zones

25. Set-up Insitu Conditions n Define in situ conditions in terms of: *Stresses (total or effective) *Pore water pressures (total or excess) *Preconsolidation pressure (for critical state soil models) n Use the Stress Converter to automatically calculate the in situ conditions

26. Set-up Increment Blocks n An analysis is divided into a number of discrete stages called Increment Blocks n Use Increment Blocks to: *Model each stage of a construction sequence *Apply new or modified boundary conditions *Apply new or modified loads *Allow consolidation to occur *Control numerical accuracy

28. Example Analysis The following screens are taken from an analysis of the construction of a deep basement close to two tunnels of London Underground’s Central line.

29. Stage 1 In Situ Finite Element Mesh

31. Stage 2 Install tube tunnels

33. Stage 3 Install top slab and simulate overhead road

35. Stage 4 Excavate beneath top slab to base of second slab

37. Stage 5 Install second slab

39. Stage 6 Excavate beneath second slab to base of third slab

41. Stage 7 Install third slab

43. Stage 8 Excavate to bottom of base slab and install it

45. Running An Analysis n The analysis can be run through the Pre- Processor, or directly by command line n Progress messages are issued whilst the analysis is running n Once complete, all analysis output is stored in Microsoft Access database file

46. Post-Processing *Graphs *Contour Plots *Stress State Plots *Deformed Mesh Plots *Report Generator n Analysis output can be visualised and reported on in the SAGE CRISP Post- Processor n Post processing features include:

52. New in version 4 n 32bit compatible for Win95 and NT n Introducing Layers for easy meshing and selection of superimposed elements. n Find feature for searching location of elements and nodes in a mesh. n Animated display of deformed mesh and stresses n Improved display of stress contours. n Improved display of stress state codes

53. New in version 4 n 3-Surface Kinematic Hardening model allowing simulation of stiffness of soils which exhibit high stiffness at small strain by tracing the soil stress history. n New Mohr-Coloumb model with non-associated plasticity, friction hardening, cohesion hardening and dilation.

54. New in version 4 n Duncan and Chang's Hyperbolic model for hard soils. n Large deformation formulation based on the Updated Lagrangian method. n Iterative solution scheme based on Modified Newton Raphson method.

58. Overview of the CRISP Consortium n The Consortium was setup in 1996 and consists of various academics and geotechnical experts in the UK. The Consortium was established by Cambridge University to take care of development of CRISP and organise courses. n In 2000 the Consortium took over the marketing of SAGE CRISP from SAGE Engineering n The Consortium’s office is based in South Bank University, London.

60. Overview of the SAGE Engineering SAGE Engineering Ltd was formed in 1991 having operated since 1984 as Structural and Geotechnical Engineering Ltd. From a background of geotechnical site investigation, SAGE had developed skills in geophysics, geotechnics, rock mechanics, structural and foundation engineering, pipeline design, and in 1994 Sage Engineering formed a partnership with Cambridge University to produce SAGE CRISP. SAGE Engineering’s USA. affiliate, SAGE Engineering Inc, was formed in 1995 by the acquisition of assets and personnel of Geocognetics, Inc., a Houston-based consulting and engineering services firm with consultants’ finite element experience dating from 1981 in Critical State geotechnics and from 1967 in structural dynamics.

61. Overview of the SAGE Engineering SAGE Engineering, Ltd released SAGE CRISP with a 2-D Windows-based graphical user interface in 1996, and in 1997 named SAGE Engineering Inc as the sole SAGE CRISP distributor in North America. In 1998 SAGE Engineering, Inc was authorized to make further developments of the SAGE CRISP program. Current projects include the development of a 3-D interface.
