The paper presents the application of the Finite Element Method (FEM) in the analysis of the stress state in artificial hip prosthesis. A virtual model of hip prosthesis was made using computer aided design systems (CAD). A better construction of this component was developed in combination with numerical analysis. Virtual model allows manufacturing the real workpiece using Rapid Prototyping technology. The article describes also the hardware and softwareaspects of the RP technology.
