Effect of Yield Strength on the Static and Dynamic Behaviours of Cylindrical Contact: Plane State of Stress

1. Introduction

Hemispherical and cylindrical contacts are two of the most fundamental problems of contact mechanics (Johnson, 1982, 1985). They are often considered to be the units of multi-asperity rough surface contact models. Fibrous and anisotropic material surfaces often consist of elongated/stretched asperities which could be efficiently modelled using cylindrical contact (Bush et al., 1979; Xu et al., 2021). Cylindrical contact analysis has been useful for modelling in different domains of analyses including electrical contact (Angadi et al., 2012; Jackson & Kogut, 2007), thermal contact (Jackson et al., 2012), mechanical seals (Green & English, 1992), cams etc.
