Characterization of the behavior of different contacts with double coating

Ilya I. Kudish, Sergei S. Volkov, Andrey S. Vasiliev and Sergei M. Aizikovich

Vol. 9 (2021), No. 2, 179–202
Abstract

This paper considers theoretically the behavior of different packets of elastic double coating on an elastic half-plane. The asymptotic expressions for the kernels of the derivatives of the normal and tangential displacements of the upper surface of the external coating are obtained and represent very complex functions of multiple elastic and geometric parameters of the coatings and substrate. Simple relationships between the substrate and coating elastic properties and thicknesses as well as acting normal and tangential stresses in various limiting cases are established, and parametric regions of their validity are determined.

Keywords
two-layered thin elastic coating, elastic substrate, normal and tangential stresses, asymptotic analysis, limiting cases
