Finite Element Analysis of LTI Carbon hip joint head
This paper mainly investigates the carbon material femoral head which is used in the semi-hip replacement. Firstly the 3-D finite element model of the acetabula contacted with the prosthesis of different materials were establised and caculate the acetabulas cotacted stress. Througt comparing the contacting stress of the acetabular, the effect of different material with quite different propertys is clearly shown. It was found that:stress concentration is much obvious in the contact area of acetabulum. Elastic modulus of the femoral head material has great impact on the acetabulas stress distribution. The greater of elastic modulus, the bigger of the greatest stress and the more obvious of stress concentration. Therefore, semi-hip replacement with the low elastic modulus carbon femoral head can significantly reduce the acetabular wear and alleviate pain.
