Simulation of structural behavior is key to achieve performance requirements whilst minimizing component cost and minimizing time consuming and expensive trial-error processes. The composite structural design is carried out starting from the surface and ply-by-ply model of the component, and transferring this data automatically into the FE environment. Typical initial concept studies begin with stiffness, modal and linear static strenght analysis to quickly determine the initial layup validation. Any changes to the layup that are identified in the FE environment are promptly replicated in the ply-by-ply geometrical model to assess manufacturability, cost and package implications. In this way there is always one master version of the composite layup. For more complex designs, non-linear analysis is required for the simulation of geometrical non-linearity or in some cases damage propagation.

A progressive reporting of activities allows a detailed monitoring of design process.



Linear-static analysis based upon specifics of stiffness and strength. Linear, steady-state, and transient heat transfer with thermal-mechanical analysis for stress and displacement control.

Linear-dynamic analysis to meet specifications of modal behavior. Linear analysis for Buckling, Random loading, Spectrum response, Transient response.

Static implicit non linear analysis, with contact and gap elements. Non-linear analysis for dynamics and crash behavior investigation using implicit and explicit methods.

Size and shape optimization is employed to fine-tune the layup to minimize mass while meeting design targets.
