Axisymmetric contact problems for an elastic layer resting on a rigid base with a Winkler type excavitation

摘要

Axisymmetric contact problems for an elastic layer pressed by a rigid sphere or by a rigid flat cylinder are considered. It is assumed that the layer rests on the rigid half-space with a near-boundary cylindrical excavitation which is filled with a deformable material. This material is modelled by a Winkler medium. The Hankel integral transforms are applied and the problems are reduced to the system of integral equations. The numerical analysis is performed to investigate the contact parameters and the deflexion in the excavitation zone. Results are presented in diagrams. (C) 2002 Elsevier Science Ltd.
