How Ansys Solver Derives Coefficients in Tsai-Wu Failure Criterion

  I'm curious about how the Ansys solver derives the coefficients for the whole composite in the Tsai-Wu composite failure criterion that are normally determined through material testing (F1, F2, F3, etc. which are defined in the Tsai-Wu theory: Tsai-Wu Wikipedia). I'm curious why the Tsai-Wu coupling constants are for specific materials, and not for the composite as a whole.
