The main objective of this research is to develop and implement a new analytical model that relies on a continuum damage mechanics CDM approach to predict the evolution of plastic strain and mechanical damage in a unidirectional carbon fiber reinforced composite CFC. The term damage is used only in the context of failure mechanisms associated with fracture and degradation of the stiffness. Plastic and damage evolution are related to typical failure mechanisms on composite materials such as fiber, inter-fiber, and intra-fiber fracture. The plastic strain surface is defined based on...
