The analyses of deflection, curvature, stress and bending moment of the rectangular plate which is subjected to any load under any boundary condition have been done in elastic range. However, in elastic-plastic range the non-linearity of stress-strain law of steel brings us much difficulties to continue the analyses of above mentioned problems. In this paper, the authors treated on square sandwitch plate as a simplified model of solid plate, and obtained the results of its elastic-plastic analysis of deflection, curvature, stress, bending moment and the patterns of the development of the plastic zone. The Prandtle-Reuss' relation between the stress increment and the strain increment which is based on the flow theory of plasticity is used for the plastic analysis and the fundamental equations are replaced by finite difference ones and solved numerically by iterative methods. In this papar, the linear hardening stress-strain law and the von Mises yield condition are used.
