Investigation The Effect of Clearance and Body Weight on The Contact Pressure of Metal on PCU Hip Prosthesis using Finite Element Method

A common problem with artificial hip replacements is increased wear of the material in contact. Materials that are contact result pressure caused by patient's daily activities so it triggers wear. This study adopts a finite element method (FEM) to predict joint, studying behavior joint prosthesis has clearance under certain load. The aim this was observe as function and body weight. modeling uses metal femoral head polycarbonate urethane (PCU) acetabular cup. Contact hard deformable material. Four variations (0.001, 0.005, 0.01, 0.016) three weight (500N, 700N, 1000N) were used study. simulation results show lower distance weight, pressure.
