Implementation of continuum damage in elasto- viscoplastic constitutive equations

Modelling of the continuum damage framework, is developed for application in the elasto-viscoplastic Chaboche constitutive model. A brief description of the basic variant of the Chaboche model equations is given, followed by a discussion of the most important assumptions necessary to obtain evolution of the continuum damage model and its appli-cation to the open FE commercial program. A consistent presentation of the two proposed approaches is followed by numerical examples
