Abstract (EN): Aseptic loosening of cemented hip implants frequently indicates failure by shear or tension of the cement-bone interface. An element-failure algorithm is proposed for the simulation of the mechanical behavior of the cement-bone interface until failure, under tensile and shear loading. To validate the model proposed, analysis on the cement-bone interface properties (elastic modulus, strength and thickness) and failure criteria, as well as mesh convergence analysis, were performed. Numerical results showed that the proposed element-failure method is able to determine the initiation and progression of interface failure in cemented hip replacements.
