Abstract

The present study focuses on a developed crack density-based model for evaluating the material properties of an orthotropic composite ply containing a specified matrix-cracking density. Furthermore, more complementary details of this model, including a closed form solution for evaluating the stress fields as well as stiffness degradation of a damaged ply, will be presented. The derived relations will be applied for evaluating the master plot curve, which is applicable for obtaining the finite fracture toughness (G_mc) of laminated composites. The obtained results will be compared with the available experimental results.
