Effect of friction on a receding contact between a perfect-fit pin, bushing and plate

This paper presents the results of a finite element analysis of a receding frictional contact between a perfect-fit pin inside a bushing, which is in perfect fit with a hole in a plate. The elasticity of all three bodies is taken into account, and the bodies are considered as isotropic. The problem is analysed within the frame of linear theory of elasticity and under the assumption of plane strain conditions. The fact that the presence of friction affects contact pressure distributions is well known, and the results obtained for the structural problem presented here are a novelty in this field of study. In addition, the results are analysed for several different geometries, which gives an insight into the influence of the ratio between the pin radius and bushing thickness.
