Enhancing the predictive capabilities of a composite plasticity model using cohesive zone modeling

One of the challenges in building a predictive numerical model for laminated composites is the ability to accurately model delamination. In this paper, a modular orthotropic plasticity model that is made of three sub-models – deformation, damage and failure, is used in conjunction with a delamination model to predict the behavior of an impact event involving a unidirectional laminated composite. Both the composite and delamination constitutive...
