  • Topological Optimization for Fatigue Strength of Porous Polyurethane/Alumina composite

抄録

<p>This research aims at developing a topological optimization method for fatigue and compressive strength of Polyurethane / Alumina composite considering pores distributions. The number of artificial hip joint surgery as well as the artificial hip joint itself have been increasing due to super-aging society. However, the service lives of the artificial hip joint are still shorter than expectation due to loosening. To prevent loosening, damage behavior of porous cancellous bone should be revealed. The effect of porosities on stress concentration behavior was firstly observed and the increased values of stress concentration factors were observed, which led to decreased compressive strength of porous components.</p>
