AbstractTypically, the problem of a plate on an elastic foundation has been approached by assuming that the foundation modulus (or modulus of subgrade reaction for a soil) remains constant as the plate deforms the foundation. If one were dealing with soil as the foundation material, it can be seen from a load-deformation plot for a particular soil, that this modulus would not be constant but would decrease as the deformations increase. The purpose of this thesis is to obtain an accurate solution that uses a more realistic model for the effect of the foundation behavior in the problem. When larger deflections of the plate are encountered, the results of the analysis using a non-linear model for the foundation differ substantially when compared to results using a linear model.
