Tsai-Wu theory is a modification of the Hoffman theory and the phenomenological material theory of fracture, which is widely used for anisotropic composite materials having different tensile and compressive strengths. The disadvantage of this criterion is that it (like the Tsai-Hill theory) is better applied when the tensile and compressive forces are not equal..
For a flat stress state, the coefficients of the Tsai-Wu strength criterion have the following values:
Then the criterion looks like this:
