Based on the simulations, the optimization analysis is performed on the anti symmetric laminates. Higher Order Shear Deformation plate theory is utilized to predict the deformation of the plates. To determine the mode of failure for composite plates, a failure criterion with the existence of coupling terms is employed. The selection of this criterion is made, because of its uniqueness that it includes the coupling terms, which relate the interaction between the longitudinal stress and the transverse stresses.
