A finite element methodology for wear-fatigue analysis for modular hip implants

► Fretting analysis on stem/head contact of a hip implant. ► Tribological and profilometry tests on stem/head material combinations. ► 2D axisymmetric fretting wear-fatigue FE analysis for stem-head contact. ► Comparison of fretting performance between forged Ti64 and DMLS Ti64. ► Development of an FE method on fretting wear-fatigue analysis of hip implant.
