The paper presents the solving of the problem of the stress states in the ceramic head of hip joint endoprosthesis. This problem is very important today, because there had occurred the destruction of the ceramic head among a non-negligible number of patients. The values of the head stress and reliability are significantly influenced by the existence of the modeled production inaccuracies on the head...
The paper considers stress and reliability analyses in the total endoprosthesis ceramic head, the production inaccuracies of the head-shank conical joint are considered. The fem program system ansys is used for computational modeling of stress in the system, weibull weakest link theory is used for determination of the ceramic head fracture probability. The stress results are different from the fracture...
