Stiffness reduction of cracked [O~/!X$], laminates is analyzed by variational methods on the basis of the principle of minimum complementary energy. For this purpose admissible stress systems are constructed which satisfy equilibrium and all boundary and interface conditions. The optimal stress fiel
The stiffness reduction of symmetric hygrothermal aged angle-ply laminates containing a cracked mid-layer is predicted by using a modified shear-lag model. The material properties of the composite are affected by the variation of temperature and moisture, and are based on a micro-mechanical model of
The effect of matrix cracks on the eigenfrequencies of unsymmetrical, cross-ply laminates is investigated. The cracks are modelled as aligned slit cracks across the ply thickness and transverse to the laminate plane. The distribution of cracks is assumed statistically homogeneous for a given average
