Abstract

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 models are built entirely using experimentally obtained data. The delamination model that uses cohesive zone elements, is built using data obtained from double cantilever beam (DCB) and end-notched flexure (ENF) tests. An impact validation test is simulated, and the results are compared both qualitatively and quantitatively with experimental results to validate the both the cohesive zone element (CZE) parameters and the composite material model. The paper concludes with a summary of the work and ongoing work to improve experimental procedures and the constitutive model.
