Hi all!!!

General theories of failure of laminated composites are Tsai-Hu, Tsai-Hill, Maximum stress and maximum strain. These thoeries do not specify which component (fiber or matrix) of lamina fails.

Sigma_zz, sigma_xz and sigma_yz are out of plane stresses which cause delamination failure of laminated composite structures.

I am looking for exclusive theories of failure which govern delamination failure in laminated composites. I request those who work in this area to help.

Thanx in advance,

Regards,
