Abstract : Diagnostic experiments indicate that given a reliable lamina failure criterion, the laminated plate theory can provide a reasonable predic-tion of the laminate failure. Additional refinements lie in the areas of: accounting for non-linear stress- strain relationships in laminated plate theory; analyzing in detail the intra-lamina stresses; using experimental capabilities of external pressure for tubular specimens; and developing the higher order failure tensor for direct phenomenolo-gical failure characterization.
