Finite Element Modelling of A Human Femur

Sarah McIlwain


Medical practitioner and researchers have recently acknowledged the benefit of using Finite Element Analysis (FEA) tools to investigate the stressful effects that current orthopaedic procedures could have upon load bearing structures within the human body. FEA is a cost effective and flexible method of analysing the effects of static and dynamic loads upon one of the most common fracture locations within the body; the human femur [8]. In order to facilitate efficient analysis, a virtual femoral model has been constructed using the ANSYS finite element modelling software. The model’s mechanical properties and ultimate strengths have been verified using data gained from both physical composite bone testing and the preliminary literature review. Additionally, conclusions about the necessity of modelling thigh muscles and ligaments in order to improve numerical accuracy were drawn based upon factors of safety associated with static testing of maximal dynamic loads.
