An Automatic Analysis of the Elastic Contact Problems By the Point-Matching Method

Up to now, to analyse the problems of contact between two optional elastic bodies is very difficult because the contact area S varies nonlinearly with the contact load Ρ or displacement δ. This paper deals with the development of an automatic procedure for the analysis of the general problems of elastic bodies in contact. In this procedure, the point-matching method, which is utilized for several contact problems, is introduced into the automatic design system to form an optimum pattern. Moreover, by applying the above mentioned method the identation problem of a circular or wedgewise rigid punch into an elastic band plate is analysed in detail.
