Abstract

This study presents a semi-analytical solution method to perform both pre-buckling and bucking analyses of laminates having a cutout by employing a simple {3,0}-order plate theory. In this theory, the in-plane and out-of-plane displacement fields are respectively assumed in the form of cubic and uniform through-the-thickness expansions. The cubic expansion ensures the correct behavior of transverse shear deformations while satisfying the condition of zero transverse shear stresses at the laminate faces, thus avoiding the computation of the shear correction factor. This semi-analytical method utilizes the principle of stationary potential energy in order to derive the equations of equilibrium for the pre-buckling and buckling states of the laminate with a cutout. Buckling load comparisons against the classical laminate and higher-order theories prove this semi-analytical method credible.
