In the conventional limit analysis, it is supposed that the circumferential plastic hinge line is formed at the same position in a plate. However, there would be a contradiction in this assumption and it is necessary to re-examine the hypothesis used in the conventional limit analysis. Because, from our previous experiments, it has been confirmed that the plastic hinge line spreads gradually. The elastic analysis under the constrained support conditions both inner and outer peripherally, which the bending moment and the membrane force act at the same time, is described in this paper. Especially, as the first step for consider the model of numerical analysis, theories of two kinds of large deformations will be compared with the theory of an infinitesimal one, and we investigate how those results influence the model of the plastic analysis.
