Abstract: Large deflection dynamic response of annular plates resting on a two-parameter elastic foundation is investigated in this paper by a new effective approach, which consists of a differential quadrature representation together with a single perturbation techneque in the spatial domain and a three-point recursive relatio nhip for the dynamic response in the time domain. The effect of foundation confi guration on the deflection response is also discussed and demonstrated in numerical examples.
Keywords: two-parameter foundation, annular plate, nonli near dynamic response, the differential       quadrature method, the perturbation technique.
