Models for Material Damage with Viscoplasticity
Models for Material Damage with Viscoplasticity
Altstadt, E.
Abstract
Two models of material damage occuring with viscoplasticity are presented:
1. accumulation model based on rupture strain
2. constitutive model based on the volume fraction of creep cavities
The creep model for porous material is developed by numerical simulation experiments with a FE model representing the simplified microstructure of a representative volume element.
The damage accumulation model is integrated into ANSYS via the user programmable features.
Keywords: ANSYS; Viscoplasticity; Damage; Finite Element Method; Porous Material
