In the bending analysis of thin elastic plates subjected to lateral load, formulas based on the linear theory are quite satisfactory, provided that the deflections are small compared to the plate thickness. If deflections are of the same order of magnitude as the plate thickness, the linear theory may yield results which are erroneous and therefore a large deflection theory should be applied. The nonlinear Berger equation for large deflection problems of plates and the point-matching method are utilized to obtain solutions for deformation in rectangular isotropic plates with a circular rigid body at the center. Numerical solutions are presented in order to illustrate the influence of the rigid body size on the deflection distribution in plates subjected to concentrated load at the center of the rigid body. The numerical procedure is easier than other procedures, such as the boundary element method, and reasonable results are obtained.
