Abstract:

The transverse loading state of a laminate with elliptical delaminations is divided using the principle of superposition, so that the problem of delamination can be reduced to the analysis about the additional displacements and stresses caused by the additional shear loading acting on the delamination surfaces;thus a simple mechanics model about delamination area is established. Then, a trigonometric series is applied to describe the displacement mode satisfying the boundary conditions. At last,...
