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.

In the paper the real-time system based on FPGA applied to control the delay time in feedback loop of the Self-excited Acoustical System is presented. The system can be used for stress change measurement in elastic constructions. Stress changes manifest themselves in small but detectable variations of resonance frequency. This phenomenon can be used to indirect measure stress changes in the material. In the article the limits of the measurement system which occurred during research on the analogue version of the system were eliminated by applying FPGA technology.
