چکیده :

In this study, stress and displacement analysis of a titanium hip joint implant was conducted using the Finite Element Method and the Abaqus software. The objective was to examine the effect of design and material composition on the mechanical performance of the implant. The implant design included a solid model created using SolidWorks software. For the simulation, two titanium alloys, TI_6AL_4V and TI_13NB_13ZR, were used, which are suitable for medical applications due to their high biocompatibility.After designing, meshing, and applying boundary conditions and loading similar to walking conditions, the process was completed. The results of relative displacement showed that both materials have displacement values within the permissible range (40 to 150 micrometers), which is beneficial for proper bone growth. In terms of stress distribution, the TI_13NB_13ZR alloy showed better performance compared to TI_6AL_4V. Ultimately, the design with the material TI_13NB_13ZR was introduced as the best option because it generates the least displacement and the lowest stress concentration.
