Abstract

This anisotropic damage model was developed based on the internal state variables of the irreversible thermodynamics processes by the second authors and his co-workers. This model was applied to a class of composite materials with the use of the micromechanical generalized cell model (GMC) in order to analyze the elastic-plastic behavior of the damaged metal matrix composite. Although derivations were made for elasto-plastic behavior analysis, the numerical example was solved for only the elastic response for a single layer of damaged composite material. In this paper an efficient algorithm is used for implementation of the developed anisotropic damage model. The numerical example is solved for elasto-plastic laminated composite materials in the presence of damage. The three step split operator method along with fully implicit integration scheme is used here for the computational algorithm of the damaged elasto plastic constitutive relations.
