Modeling Layered Composites the Simple Way

Composites offer tremendous weight savings, increased performance, and design flexibility for a wide range of applications

As a composites user/manufacturer, you want to limit costly and time consuming prototypes S.Riaz, E.S.Greenhalgh, M.S.P.Shaffer, A.Bismarck,  "Conference proceeding on Hierarchical carbon fibre reinforced Poly (vinylidine) difluoride composites" ECCM 14, Budapest, Hungary

The simulation of composites products is challenging because of a complex setup due to the many different materials, orientations and plies layups as well as specific failure analysis

You want to efficiently and accurately predict how well the finished product will perform

ANSYS solutions for composites let you efficiently design complex composites structures Productivity from streamlined workflows Accurate understanding of the performance of your design Optimization of your design

ANSYS solutions provide an intuitive workflow for the setup of composites models for maximized productivity

ANSYS Solutions at Repower Systems AG “The intuitive implementation of composite design development in ANSYS Composite PrepPost brought out a revolution in composite simulations. We are able to realize a continuous design process from simulation results to manufacturing including design modifications within the development.“ This is what Repower says about our composites analysis solution. Intuitiveness is a keyword here. The ANSYS Composite PrepPost solution allows users to efficiently define the most complex structures. Hendrik Mester, Rotor Blade Development, REpower Systems AG

3 steps to transform your CAD model in a simulation model Geometry cleaning Composites definition Working conditions

Composites characteristics are defined on the simulation model as you would on the real parts Single fabric and predefined stackups definitions Plies locations are defined on the geometry using fabrics or stackups

Thick composites or complex geometry will benefit from 3D modeling Automatic extrusion from the ply definition and snap to a complex shape Thick core imported from a CAD model

Assembly of composites and non-composites parts Assembly modeling and coupling of multiple physics enhance the fidelity of your simulation Assembly of composites and non-composites parts Fluid-structure coupling to import pressure fields

ANSYS solutions for composites provide all necessary results to accurately understand performance of your product

Deformations and stresses are available for the full model  The ply or ply group that fails in a multidirectional laminate; the load corresponding to this failure can be the design limit load tw(31) (0) tw(31) (0) tw(31) (0) tw(31) (0)

First-ply failure analysis computed from strengths estimates is the first indicator of composites performance  The ply or ply group that fails in a multidirectional laminate; the load corresponding to this failure can be the design limit load tw(31) (0) tw(31) (0) Global estimates help locate critical areas tw(31) (0) tw(31) (0) Local estimates help identify ply location and reason for failure

Additional information such as plybooks including weight and price estimates is also available

To further improve your design, you could investigate advanced failure modes such as crack propagation, progressive damage or drop-test analysis Crack propagation Initial crack Debonding of a composite structure Start of damage (layer 1) Progressed damage (layer 1) Progressed damage (layer 3)

ANSYS solutions will allow a faster and less expensive design of lighter and more robust products

Save your engineers time with efficient workflows and let them focus on understanding the design Composites definition Failure analysis Working conditions Geometry cleaning

Optimize your product by performing as many virtual design variations as you need before creating the first physical prototype Change the value of any dimension then update the entire model automatically Create response surfaces for optimization

Optimize the composites layout using scripts to modify ply sequences, materials…
