An interlaminar-shear-stress analysis for progressive damage in composite laminates was developed. A general governing equation set was derived for [φmn]s laminates that involves only in-plane displacements in both layers based on equilibrium, continuity and boundary conditions. The case of the crossply [0m/90n]s laminate with matrix cracks in both layers under biaxial loading was solved. Residual stresses and non-linear behavior were taken into consideration. Theoretical predictions agree fairly well with experimental data in many ways. Stress distributions for various crack densities were obtained.
