Materials selection in the artificial hip joint using finite element stress analysis

Abstract The finite element stress analysis technique can be used to optimize both design and materials selection in many load-bearing components. The study presented here considers the effect of prosthesis Young's modulus and cement Young's modulus on stresses in the prosthesis stem and cement layer. Comparison is made with previous work, and consistent trends are established. From this, a materials selection criterion is proposed, based on fatigue strength.
