AbstractComposite laminates exhibit complex damage and failure modes, such as matrix cracking, delamination, fiber breakage, and fiber-matrix interface debonding. The severity of the damage depends on laminar strength and stiffness, ply orientation, stacking sequence, fiber volume fraction, type of loading and environment. Failure occurs when critical levels of loads or deformations are reached, related to damage dependent failure criteria. Analytical computations establish laminate damage evaluations, i.e. matrix micro- and macro-cracking, fiber rupture and layer delamination. The initial, tangent and residual material properties are computed as well as damage initiation in critical zones of arbitrary composite laminate structures to evaluate stable and unstable growth, and thresholds for low strain criteria.
