Thermal buckling of hybrid angle-ply laminated composite plates with a hole

Abstract In this paper, thermal buckling analysis of symmetric and antisymmetric laminated hybrid composite plates with a hole subjected to a uniform temperature rise for different boundary conditions is presented. The first-order shear deformation theory in conjunction with variational energy method is employed in mathematical formulation. The eight-node Lagrangian finite element technique is used for obtaining the thermal buckling temperatures of glass–epoxy/boron–epoxy hybrid laminates. The effects of hole size, lay-up sequences and boundary conditions on thermal buckling temperatures are investigated. The results are shown in graphical form for various boundary conditions.
