We develop and implement material and failure models and utilize them in crash and process simulations. We also use special testing techniques (e.g. local strain measurements, torsion and biaxial tensile tests) to characterize materials and test components. By simulating various trials, we determine the model parameters and validate the practicability of new numerical methods. The effects of manufacturing processes on component behavior are paid particular attention.

Material and component deformation and failure behavior
The characterization of a material’s deformation and failure behavior sets the foundation for reliable design and numerical simulations. At the IWM, we perform specialized tests that subject the sample to tensile, compressive and shear stresses in order to determine the effects of multi-axiality and load type on failure behavior. Component tests at up to 8 MN can be carried out to validate simulations...
