Hip prostheses used to fulfill injured or fractured limbs are made by machining, casting and plastic forming. Machining is the most commonly used one. However, there are many disadvantages such as high product cost in machining. Plastic forming methods provide more effective and durable implant production than machining. In this study, hip prosthesis with a complex geometry produced by forging were analyzed using the Finite Element Method (FEM). For this purpose, three-dimensional complex

Factors affecting the production were defined as: temperature, friction coefficient and the pressing velocity. Stress distributions, temperature changes, die wears and punch forces applied to the die were examined. As a result of the study, the most suitable parameters were obtained as 500°C, 0.05 coefficient of friction and 2mm/s die velocity. Also, the obtained FEM results were examined by regression analyses.
