A FAST-SOLVING SEMI-ANALYTICAL SOLUTION METHOD FOR CONTACT PROBLEMS INVOLVING MULTI-LAYERED INHOMOGENEOUSLY ELASTIC SOLIDS

摘要

This work is concerned with the derivation of an iterative solver which allows the accurate estimation of both the contact half-width and contact pressure when an inhomogeneouly elastic solid comprising a homogeneous coating and substrate joined by a graded layer is indented by a rigid punch. A selection of numerical results are then presented illustrating the accuracy of this model.
