Abstract
This report presents an analytical approach to describe the initiation and propagation behaviors of matrix-dominant cracks in laminated composites. A rational analysis method for the phenomenological characteristics of matrix cracking is developed on the basis of ply-elasticity, fracture mechanics and effective material flaw concepts. Emphasis is placed on the basic mechanisms of multiple random cracks formation, delamination growth and interactions among cracks of differing propagation modes. Examples simulating laboratoroy coupon tests are presented to highlight the analysis method.Keywords
