Influence of different parameters on the deflection of composite laminates containing through-the-width delamination using Layerwise HSDT

The effects of different parameters of the composite laminate and delaminated area are investigated analytically under buckling load based on a developed Layerwise Higher Order Shear Deformation Theory and the results are compared with the three dimensional Finite Element Analysis. The results demonstrate the consequences of different geometrical parameters of the delaminated area, lay-up sequences and thickness of the laminate on the deflection of a composite plate containing through-the-width delamination.
