The Dynamic Response of an Elastic Circular Plate on a Viscoelastic Winkler Foundation Impacted by a Moving Rigid Body

Abstract

This work considers the dynamic response of an elastic circular plate on a half-space viscoelastic Winkler foundation impacted by a moving rigid body at a lower initial velocity. A nonlinear Volterra integral equation on impact load F(t) is deduced, and a numerical method is used to solve the equation and calculate the deflection of the plate. As an analyzed example, the dynamic response of a solid circular plate with clamped edge on the Winkler foundation impacted centrally by a rigid sphere ls computed numerically.
