Abstract
The purpose of this study is to estimate mechanical behaviors of a CFRP cup and bone based on finite element method (FEM). The details of the proposed method are as follows; Firstly, a numerical model of acetabulum has been prepared with CT image of patients, and the model of a CFRP cup are generated. The press-fit analysis, which means the estimation of the mechanical behavior to press the cup toward to the acetabulum, has been carried out with considering contact phenomena. As the examples, two kinds of cups are prepared. One is a CFRP cup, and another is a metal cup. The difference of the mechanical behaviors with both cups is discribed in this paper.
