Mechanism-Based Models for Time and Temperature Dependent Plasticity and Damage

Sophisticated deformation models can describe typical material phenomena such as strain hardening, creep, relaxation and strain rate effects, taking account of microstructural changes and their effects on the mechanics.

The mechanism-based damage models can describe crack growth under fatigue and creep fatigue loads. The models account for material properties that change with temperature and make it possible to assess the life expectancy, including the effects of thermomechanical loads.
