A quasi-brittle damage model for composite material is presented to analyze progressive failure in composite structures. A rate independent constitutive law is expressed in terms of three damage parameters by using several polynomial failure criteria and a suitable micromechanical model. In order to

An exact solution for stresses in cracked composite laminates with lay-up [0 m =90 n ] is developed in this paper. The inter-laminar shear stresses between the 90Β°and 0Β°plies are assumed to be in the form of series expansion of sinusoidal functions. This leads to the stress components in laminates h
