|Outline of Final Research Achievements
This study successfully conducted 1. experimental observation on loosening behavior of acetabular cup by cyclic loading, 2 In-situ toxicity observation of osteoblast by fretting wear 3. The effects of biological, mechanical ,chemical degradation of porous component of mechanical behavior and durability of porous bone, 4. Finite element analyses on estimation of loosening behavior of acetabular cups by the damages of interface and simulated bones. The result could systematically estimate the extent of loosening of acetabular cup subjected to cyclic loading, and the major contribution of mechanical property of porous components on the loosening behavior.
