摘要：

The buckling problem of a simply supported unbalanced sandwich plate is solved using the Rayleigh-Ritz method. The sandwich plate consists of an antiplane core, two unequal anisotropic laminated faces, and adhesive layers of finite bonding stiffness. The analysis takes into account all the possible coupling actions in faces to examine the coupling effects of sandwich buckling behavior. The buckling loads are calculated for various face lay-up angles, core to face thickness ratios, and aspect ratios. The bonding stiffness is quite critical for a sandwich plate with thick faces and stiff core when it is smaller than the threshold value.
