N2 - Artificial joints have two distinct functions. Firstly, to provide for an adequate range of motion, and secondly, to transfer the joint forces to the bone without causing failure. The chances for failure to occur depend on the strength of the implant/bone connection, and on the stresses associated with the load-transfer mechanism. In this paper the feasibilities of minimizing these stresses, thereby reducing the chances for failure, are discussed. Our attention will focus on the femoral component of Total Hip Arthroplasty (THA), made out of metal, and fixated in the bone with the use of acrylic cement. The stress patterns in this structure will depend exclusively on four aspects, (i) the magnitudes and orientations of the external loads, (ii) the geometry, (iii) the properties of the materials, and (iv) the boundary conditions, including those of the connections between the separate substructures (interfaces).
