Abstract
A successful viscoelastic layered contact model has been developed. The single layered linear
viscoelastic material is assumed to be perfectly bonded to a rigid substrate and contact a rigid
ihdenter without friction under a step load. Two cases are considered; (1) a compressible layered
material with a typical Poisson's ratio of 0.45 and (2) an incompressible layer with a Poisson's
ratio of 0.5.
This paper highlights the methodology and the results obtained under various conditions.
1 Introduction
In many applications involving contact mechanics, the tribological performance of
surfaces can be enhanced by covering them with thin layers of soft materials. The
dissimilar elastic properties of these layers to those of the substrate are of
particular interest owing to their increasing applic
