THE CRITICAL STRESS OF SHEAR DEFORMABLE ORTHOTROPIC PLATE WITH FOUR EDGES ELASTIC-ANGLE-CONSTRAINED

A method for calculating the critical stress of shear deformable orthotropic plate with four edges elastic angle constrained is proposed. Simply-supported and clamped-supported are two limiting situations. With this method, critical stresses of several kinds of rectangular plates are calculated in some degenerated cases. The comparison with other references shows good agreement, which verifies this method.
