Abstract

In this paper a new assumed stress finite element method, based on a complementary energy method, is developed, for the analysis of cracks and holes in angle-ply laminates. In this procedure, the fully three-dimensional stress state (including transverse normal and shear stresses) is accounted for. Results obtained from the present procedure, for the case of an uncracked laminate under bending and for the case of a laminate with a through-thickness crack under far-field tension; their comparison with other available data; and pertinent discussion, are presented.
