Delamination mode failure
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,
