Abstract

Finite element analysis of the contact behaviour of metal to plastic interfaces in total knee joint replacements T. McGloughlin,* J. Monoghaif "Department of Mechanical and Aeronautical Engineering, University of Limerick, Ireland * Department of Mechanical and Manufacturing Engineering, University of Dublin, Trinity College, Dublin 2, Ireland ABSTRACT Contact stress analysis of prosthetic implants has become a significant area of research in recent years with increased demand for greater levels of stress analysis of products in the preclinical phase. New techniques for contact pressure measurement have been developed (FUJI Presensor, and Tekscan) and in addition improved contact algorithms have been developed by finite element software developers. The current study uses the contact capabili- ties of MARC software to investigate the contact stress levels occurring at the femoro-tibial interface in a total knee joint replacement. The components are modelled initially using
