DYNAmore Express: Modeling Plastics in LS DYNA (Part 1) - Isotropic Modelling of Thermoplastics

#lsdyna #dynamore #cae Speaker: Peter Reithofer (4a Engineering GmbH) Note that this is the first part of our two-part series on thermoplastic modelling. The follow-up session can be found here    • DYNAmore Express: Modeling plastics in LS ...   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.
