WebThe failure criteria proposed to predict lamina failure could be divided in two main groups: a) Failure criteria not associated with failure modes This group includes all polynomial and tensorial criteria, using mathematical expressions to describe the failure surface as a function of the material strengths. Generally, these expressions The Tsai–Hill failure criterion is one of the phenomenological material failure theories, which is widely used for anisotropic composite materials which have different strengths in tension and compression. The Tsai-Hill criterion predicts failure when the failure index in a laminate reaches 1.
