Bending response of cross-ply laminated composite plates with diagonally perturbed localized interfacial degeneration

A laminated composite plate element with an interface description is developed using the finite element approach to investigate the bending performance of two-layer cross-ply laminated composite plates in presence of a diagonally perturbed localized interfacial degeneration between laminae. The stif...
