Abstract

The displacement of a plastic fluid by an elastic disc approaching a plane rigid surface oriented perpendicular to the disc axis is computed with a numerical scheme accounting for the coupled deformation of the disc and flow of plastic. The axial force to push the disc is in agreement with lubrication theory approximation. The existence of un-yielded fluid situated at the corners of the fluid region on the centre-line have been predicted, similar to the case observed for rigid disc squeeze flow.
