| Abstract | ||
| This research aims to induce the influence of nonlinear behavior material at mathematical structure by computer program for reducing the contact problem and stress state for the critical rounding profile of artificial joint. This subject computer must be modified to analysis the mechanism movement of the joint by taking different angle of rotation in the contact zone and at the edges of the joints. For the contact problem with in nonlinear material, analytical solutions are obtained for both surface pressure and interior stress field. Cases of normal and frictional contact in both sliding and partial slip conditions are all treated. The effect of the modification of the horizontal configuration on the stress distribution in rounded shapes of the joints have been analyzed experimentally using photo elastic pattern in different angles. The theoretical results have good agreement when compared with the experimental one. | ||
