Simulators have been used for a long time in industry. We identify three categories of use: training, design, and testing. We underline that for these three categories of uses, the two major areas of improvement are a ...

The model of Johnson and Cook, which includes a viscoplastic flow rule and a damage criterion, is widely used to describe the mechanical behaviour of metallic materials subjected to severe loading conditions, such as those ...

In the present work, a framework for the development of constitutive models for metallic materials in a thermomechanical context is proposed. Such a framework provides some guidelines to deal with processes involving large ...
