Original Abstract

The problem of the stress in the head of the hip joint endoprosthesis is solved by FEM. These shape variants of the contact areas were taken into account: accurate variant, deviation from the nominal conicalness, no roundness contact surfaces (modelling by the help of elliptically shaped), indirectness of contact surfaces, combination of no roundness and conicalness. The maximum of the first principal stress in the ceramic head decreases with the increasing of the angle of the loading. Deflections of the type no roundness create the highest values of maximum stresses in the head.
