Finite element modeling of the contact interaction of the acetabular component and acetabulum

Abstract

© 2019 IOP Publishing Ltd. Degenerative-dystrophic lesions of large joints arethe most common diseases. Up to now, the problem of hip arthroplasty with dysplastic coxarthrosis has not been completely resolved. The most interesting is the modeling of the contact between the cavity and the neck of the thigh. This paper consists of verification algorithm for acetabular component model. Particularly contact displacements and stresses fields are considered. The main idea of this method is comparison between analytical solution and solution which we get by means of the finite element method. This comparison is used to verify contact elements and contact settings between contact and target area. For doing that the nonstationary contact problem with moving boundary conditions had been solved analytical. Algorithm of the verification of this problem is described below.
