Models for Material Damage with Viscoplasticity


Models for Material Damage with Viscoplasticity

Altstadt, E.

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.
