摘要

The compressive stability of anti-symmetric angle-ply laminated plates with particular reference to the degrading influence of membrane-flexural coupling is reported in this paper. The degree of membrane-flexural coupling in the laminated composite plates is varied, essentially, by altering the ply-angle and the number of plies in the laminated stack for a given composite material system. The coupled compressive buckling solutions re determined in the paper using the finite strip method of analysis and the buckling Displacement fields of the strip formulation are those which are able to provide zero in-plane normal movement at the edge Boundaries of the laminated plates.
