A thermodynamically consistent continuum damage model taking into account the ideas of CL Chow

Abstract

This paper deals with a thermodynamically consistent framework to model inelastic deformation behavior and evolution of anisotropic damage in ductile metals. The theory is based on the introduction of Helmholtz free energy functions formulated with respect to damaged and fictitious undamaged configurations. Plastic behavior is modeled with a yield condition and a flow rule. In a similar way, damage behavior is characterized by a damage condition and a damage rule, both depending on stress state to take into account different damage and failure mechanisms. The emphasis is on contributions of CL Chow in the field of damage mechanics, demonstrating their remarkable influence on the proposed phenomenological model.
