Abstract
Latterly, the polycarbonare urethane (PCU) has suggested a viable substitude to conventional bearings. The aim of this study is to determine the von Mises stress and contact pressure as a function of different of acetabular cup thickness. The analysis of this study was conducted by the finite element method. Six variation of acetabular liner thickness (5mm, 10mm, 15mm, 20mm, 30mm, and 40mm) were used in this simulation. The contact pressure was determined to predict the wear performance of PCU acetabular liner. The result shown that the thicker of the acetabular liner, the smaller the contact pressure and the smaller the contact radius. Thus predictable that the thinner the PCU acetabular liner, the higher the wear rate
