Magneto-electro-elastic materials are multiphase smart materials which exhibit coupling between electrical, magnetic and mechanical energy fields. Due to this ability, they have been the topic of numerous researches in the past decade. Buckling behavior of a multiphase magneto-electro-elastic rectangular plate with simply-supported boundary condition is investigated based on the Reddy’s higher-order shear deformation theory. Gauss’s laws for electrostatics and magnetostatics are used to model the electric and magnetic behaviors of the plate. The partial differential equations of motion are reduced to ordinary differential equations by using the Galerkin method. Then, the closed form expression for the critical buckling load of the considered plate is obtained. Some examples are presented to validate the study and to investigate the effects of some parameters on the critical buckling loads of the multiphase magneto-electro-elastic rectangular plates. It is found that the buckling behavior of the Magneto-electro-elastic plate is dominated by the elastic properties of the plate, and magneto-electric coefficients increase the critical buckling load of the plate slightly.
