Abstract

In a previous paper, a method of solution has presented for the stress concentration problem of an elastic infinite plate with a circular rigid inclusion under harmonic vibration loads. It was assumed that the vibration loads act at two points symmetrically located to the inclusion. In this paper we assume that a vibration load act at a point in an infinite elastic plate with a rigid circular inclusion, under plane strain conditions. A fundamental solution of the two dimensional elastodynamics for harmonandic vibration problems is applied, as similar to the previous paper. Displacements of the inclusion and stress distributions around the inclusion are investigated.
