Numerical Simulations of Tension Tests with a new Rate and Temperature Dependent Continuum Damage and Fracture Model
The new continuum damage model is based on a general thermodynamic framework for the modeling of rate and temperature dependent behavior of anisotropically damaged elastic-plastic materials subjected to fast deformation. The ...
