Effect of the Stacking Sequence

Difference in the elastic constants in the radial direction between the -45° and 90° layers 

Fiber direction of the layer just above the delamination Fiber direction of the layer just below the delamination 

A theoretical study, Rayleigh-Ritz approximation and finite element analysis were performed to obtain solutions at various levels of simplification for the damage problem in composite plates and to clarify the mechanism of the initiation and
