Original Abstract

The paper deals with the problems of the stress and failure probability of the ceramic head of hip joint endoprosthesis. There are considered the macro and micro shape deflections of the contacted cone areas, the values are given from the 3D measured device IMS UMPIRE. The macro shape deflection is different conicity of the contacted parts, micro shape deflections are the local shape deflection which are added with the macro shape deflections. The problems of the stress and probability of failure are solved using computational modelling: stress states are calculated by FEM, failure probability is based on the Weibull weakest link theory. The failure probability of the ceramic head for the random position against the stem will be analysed in detail.
