The failurecriteria are determined by the material's strength properties, which are characterized by a set of constants obtained through experimental testing. From a practical standpoint, the Tsai-Wu failure criterion is used in structural analysis and design toensure the safety and reliability of ...
However, the Tsai–Wu criterion has been used as the point of departure for simplified criteria [18,123], which strongly reduces the number of constants. Fenech and Keaveny [123] used a simplified Tsai–Wu criterion to predict the fracture load on trabecular bovine femurs with less than 20%...
Remarkably, this equation is identical to the Tsai–Wu failure criterion, Eqn (2.5), when the constants in the two equations are equated as follows: (2.9)F1=A1,F2=A2−A3,F11=B1,F2=B2,2F12=C12,F66=A4 Thus, using a tensor polynomial, as done by Tsai and Wu (1971), or a polynom...

A modified Tsai-Wu criterion for a plane stress state, required in the multi-criterion design of thin-walled composite structures, has been presented in this study. This criterion can also be used to determine admissible stresses in individual layers of a multi-layered composite with respect to ...
The determination of the normal interaction term, F12, in the Tsai-Wu polynomial strength criterion, using a single uniaxial strain test is proposed. The appropriate formulae are derived and it is explicitly shown how F12 depends on the elastic constants of the maternal. Two other simple ...
