Note that this is the second part of our two-part series on thermoplastic modelling. The first session can be found here [ Ссылка ]

The knowledge of physical material behavior is essential for the simulation of dynamic load cases. This contribution gives an exemplary overview of typically used material models for thermoplastics (e. g. *MAT_187, *MAT_215, …) considering the different mechanical phenomena (general yield surface, anisotropy, damage and failure).

Over the last years, 4a engineering GmbH has developed the testing system IMPETUS® and the software VALIMAT® to determine the strain rate dependent material behavior particularly of plastics and composites.
This state-of-the-art solution offers a software driven workflow considering different test setups (bending, tension bending, tensile, puncture, component) to efficiently generate validated ready to use material cards.
