In this paper authors present numerical-geometrical models of cemented artificial bone replacements which consist of stem with head, layer of bone cement and femur bone all created in ABAQUS CAE 6.4 environment. Results of principal stresses analysis in bone cement layer under static load are computed using FE method. The influence of eccentricity between stem and femur, as well as influence of elastic constants are discussed. The direction of stress vector leading to maximal tensile stress has been estimated.
