The accuracy of any FEA is related to the quality of the material models describing the material behaviour. Dependent on both the materials and the nature of the problem, different complex material models must be calibrated and applied. Our simulation experts built up vast knowledge in selecting most suited material model for each specific purpose. Typical models capture the non-linear material behaviour of plastics or the anisotropic stiffness and strength of composites. Advanced models additionally cover time- and rate-dependent material properties such as viscoelasticity or strain rate dependency of polymers.

Many safety related applications require to assess how they behave after loads exceed the integrity limits. Next to an accurate prediction of material failure, proper modelling of interactions of parts is key. Our simulation experts are very experienced in modelling complex applications undergoing crash loadings, such as car child seats. This allows optimising the integrity of those products. But our engineers can even go further and include whole dummy-models into the models allowing to evaluate and optimise dummy-accelerations. Dependent on the problem, we apply either FE- or Multibody dummies.
