Effect of Trapezoidal Shapes on the Thermal Buckling Behaviour of Perforated Composite Plates

Abstract Thermal buckling study on the symmetric laminated composite trapezoidal plate with a circular cutout subjected to uniform increase in temperature for various boundary conditions is explored this paper. In mathematical model, first-order shear deformation principle employed accordance variational energy system. For acquiring thermal temperature, nine-node heterosis relation has been used finite element formulation. By correlating present findings accessible literature, effectiveness of formulation verified. The impact different parameters, such as shape, size, ply-orientation, edge and width thickness ratio have considered effect each parameters characteristics under temperatures. It observed from that parametric investigation significantly affect behaviour plates.
