The paper presents an analytical study of the behavior of a rigid-perfectly plastic circular foundation plate indenting an elastic two-parameter soil layer (Vlasov soil) under the action of a statically increasing applied load. Closed-form solutions are obtained for critical Loads, maximum surface settlements, foundation deflections and soil reactions in terms of the load intensity, after the plate has been transformed into a mechanism. Two distinct phases of metaplastic behavior are identified depending on whether or not full contact is maintained between soil and foundation. The results are compared with those obtained for a Winkler space and an elastic continuum halfspace.
