Description
Summary:This paper presents the workflow for creating a 3D finite element model of a cementless femur-implant when in single leg-stance, using state-of-the-art computer-aided design software and a finite element solver. The model consists of two geometries for the cortical and trabecular bone tissue of the femur bone, and two geometries for the stem and femoral head of a commercial implant. Each part is assumed to behave as linear isotropic material. Although relatively simplistic in its form, the presented 3D finite element model can capture the area of higher Von Misses stress concentration compared to other models in the literature.
