Abstract
A bending analysis is presented for cross-ply laminates containing matrix cracks. The cracks are modelled as aligned slit cracks across the ply thickness and transverse to the laminate plane. The distribution of cracks is assumed to be statistically homogeneous corresponding to an average crack density. The results are given for symmetrically and antisymmetrically laminated plates with a given density of matrix cracks. The effect of reduction in the laminate stiffness is studied by plotting the ratio of the centre deflection of cracked and uncracked laminates against the aspect ratio, crack density, and relative layer thicknesses. It is observed that the amount of increase in the plate deflection depends on the stacking sequence as well as on the relative thicknesses of layers.
