Abstract

This paper presents contact pressure prediction results based on numerical solution using implicit and explicit finite element method (FEM) verified by Hertzian contact theoretical solution. The contact pressure distributions are investigated for a simple cylinder-on-flat contact configuration model subjected to constant normal load. The FEM analysis is performed on two different aeroengine materials; Ti-6Al-4V and Super CMV (Cr-Mo-V) alloys. The predicted characteristics of the contact pressure distributions and the contact half-width lengths are verified with the Hertzian contact theoretical solutions. The results show that both implicit and explicit FEM are comparable with the Hertzian theoretical results. The difference of the calculated maximum contact pressure is less than 1%. The explicit method gives better agreement in terms of maximum contact pressure while the implicit approach has a better agreement in predicting the contact half-width length compared with the Hertzian contact theoretical solutions.
