Usage of a Rate-Dependent, Elasto-Plastic Cohesive Zone Mixed-Mode Material Model for Spot-weld Modeling
Currently, there are several material models implemented in LS-DYNA which are more or less capable to simulate a spot weld behavior under crash conditions. The material parameters for crash simulations are determined by comparing the ...
