“…The application field of CDM theory is very extensive: the theory has been used to describe fatigue , creep , biomechanical problems , brittle or ductile fracture or fracture related to impact problems. In this paper, we focus on ductile damage for which there are a lot of damage models (a more detailed bibliographical study of macroscopic ductile damage models can be found in Jeunechamps ): let us cite for example Lemaitre's model , Goldthorpe's model , Geers’ model , Cochran and Banner's model , Bonora's model , Johnson‐Cook's model modified by Borvik and Langseth and Longere's , Omerspahic's and Zhu's anisotropic models.…”

SUMMARYThis paper aims at presenting a general consistent numerical formulation able to take into account, in a coupled way, strain rate, thermal and damage effects on the behavior of materials submitted to quasistatic or dynamic loading conditions in a large deformation context. The main features of this algorithmic treatment are as follows: A unified treatment for the analysis and implicit time integration of thermo‐elasto‐viscoplastic constitutive equations including damage that depends on the strain rate for dynamic loading conditions. This formalism enables us to use dynamic thermomechanically coupled damage laws in an implicit framework. An implicit framework developed for time integration of the equations of motion. An efficient staggered solution procedure has been elaborated and implemented so that the inertia and heat conduction effects can be properly treated. An operator split‐based implementation, accompanied by a unified method to analytically evaluate the consistent tangent operator for the (implicit) coupled damage–thermo‐elasto‐viscoplastic problem. The possibility to couple any hardening law, including rate‐dependent models, with any damage model that fits into the present framework.All the developments have been considered in the framework of an implicit finite element code adapted to large strain problems. The numerical model will be illustrated by several applications issued from the impact and metal‐forming domains. All these physical phenomena have been included into an oriented object finite element code (implemented at LTAS‐MN 2L, University of Liège, Belgium) named Metafor.Copyright © 2013 John Wiley & Sons, Ltd.
