Micro Abstract:
An isotropic gradient-enhanced damage formulation is coupled to finite von Mises plasticity. In the context of finite elements an additional field variable, representing nonlocal damage, is introduced. In a multisurface approach, the evolution of damage and plasticity are governed by their respective criteria. Simulation results are compared to experimental data to verify the model.
