If a material is not available in the makross material database, or if specific characteristics need to be captured (temperature behavior, splitting, shearing, delamination of surface layers, etc.), we determine the required material parameters and develop suitable models.

We go far beyond simple parameter fitting. Using physically meaningful FEM modeling and representing material behavior through differential and evolution equations, we capture load-, speed-, impulse-, development-, and history-dependent behaviors.

Multi-component and layered structures, as well as orthotropic, transversely orthotropic, or generally anisotropic behavior, are simulated with the appropriate materials. For glass-fiber reinforced plastics, anisotropy can also be accounted for through prior injection molding simulations.
