Abstrakt (anglicky)
   In this paper an experimental investigation of hip replacement implant is presented. The longterm stability of hip implants depends, among other things, on the loads acting across the joint. The force magnitudes are of interest, and the modified standard investigation of an implant was performed. The results indicate that forces occurring in vivo can be much greater than the recommended test values, and can cause implant stress field changes and implant stability problems. An analysis of titanium alloys that are used as biomaterials in biomedical applications, such as artificial joint implants, is also presented from a fracture mechanics perspective. It is shown that it is necessary to understand the fatigue crack initiation and propagation characteristics in order to prevent catastrophic failure of the implant. The fracture behaviour of Ti-6Al-4V is investigated by means of standard fracture mechanics tests.
   The results indicate that this new optical stereometric measurement methodology produces good results in investigation of fracture behaviour of bimetallic materials.
