Abstract
AbstractIn this contribution a finite element model for the three dimensional investigation of hip joint contact is described. A shell‐like interface element with variable thickness is developed for modelling fluid flow in the synovial gap. For this purpose the Taylor‐Hood element is extended in order to take a spatial thickness distribution and local thickness changes into account. The interaction between the synovial fluid and the cartilage layers is solved by a staggered iteration using an artificial compressibility method. Cartilage is modelled using the theory of porous media and three dimensional geometries are reconstructed from medical imaging data. (© 2011 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
