# ANSYS help

• posted

Hi,

I started working on Ansys this summmer, so I'm relatively new. I'm studying first-ply failure analysis of composite laminates. Right now I'm just trying to verify numerical examples, but I can't seem to get the theoretical values. Just wondering if anyone on here could model this simple plate and let me know what results they get.

Here are the specifics:

• 16 layers [45/-45/0/90/45/0/-45/90]s
• rectangular plate (9x5 inches), with the long side being the x-direction, short side being the z-direction
• Ex=19.2e6 psi, Ey=Ez=1.56e6 psi, G12=G13=0.82e6 psi, G23=0.49e6 psi, nu12=nu13=0.24, nu23=0.49, X_tension=219.5e3 psi, Y,Z_tension=6.35e3 psi, X_compression=246e3 psi, Y,Z_compression=6.35e3 psi, S12=S13=12.6e3 psi, S23=9.8e3 psi
• Ply thickness = 0.005 in./ply

Specifically I'm looking to determine the first ply failure loads using max. stress theory, Hoffman, Tsai-Wu, and Tsai-Hill.

Any help is appreciated. Thanks,

CS
