Hi,
Thank you but I'm already able to plot the tsai wu failure indices. My question is about the fact I don't get the good failure indices even if I have the good stresses in the laminate.
Hello everyone,
I'm currently doing a finite element analysis of a composite plate (45/0/0/-45/90/-45/0/0/45) under tensile load.
I'm using 2 softwares to calculate the F.I. according Tsai Wu theory.
Patran/Nastran gives me : FI (90deg ply) = 0.65, FI (45deg ply)=0.25 and FI(0deg ply) = -0.1...
