For high critical loads, Hoffman/Tsai-Wu give bigger failure indexes than Max Stress and Tsai-Hill, therefore are more conservative. A further checks have been performed by considering a different orientation of the plies: [+45°/0°/-45°] ; [45°/0°/90°].

NettetTo calculate the margin of safety for the Tsai-Wu failure criterion, we must first determine the value of the proportionality factor α such that the state of stress given by ασ 1, ασ 2, and ατ 12 gives a failure index F of 1. To calculate the value of α, we rewrite the first equation in this section:.
