What is the Tsai-Hill failure criterion?

The Tsai-Hill failure criterion is a phenomenological material failure theory widely used for anisotropic composite materials that possess different strengths in tension and compression. It predicts that a laminate will fail when its failure index reaches a value of 1. As part of material failure theory, it helps evaluate conditions under which solid materials fail under external loads.

What we know

• The Tsai-Hill failure criterion is a phenomenological material failure theory used for anisotropic composite materials. [1, 2]
• It is applied to materials that have different strengths in tension and compression and predicts failure when the failure index in a laminate reaches 1. [2]
• Material failure theories are expressed in the form of various failure criteria which serve as functions in stress or strain space separating failed from unfailed states. [4]
