ABSTRACT
The presence of a cutout in a laminated composite plate is of interest to the analysts. The main objective here is to study the interaction curves for a laminated composite plate with a centrally located cutout subjected to in-plane and shear loading, using a simple higher-order shear deformation theory based on four displacement functions (u0, v0, wb, ws) instead of the five that are commonly used in most higher-order theories. The finite element method is employed to study the buckling of laminated plates.
