Abstract

The scope of this report is to present the non-linear finite element method (FEM) calculations for two artificial hip joint implants (system composed of a spigot, head and cup). For the implants the influence of the boundary conditions, the variation of the taper angle difference, the coefficient of friction between the spigot and the head and also the material of spigot and head on the stress distribution in the system are determined. For each of the two implants, based on the designs of the producer Metoxit AG, an axisymmetric FE model was generated. Note that the head of the two implants possesses different bore depths. The geometry of the spigot and cup are similar in both models. The calculations were carried out with ABAQU
