Abstract: The recent trends in numerical methods and computational techniques in the field of biomechanics facilitate to solve complex problems encountered in the assessment of the strength and reliability of structures and implants. In the present investigation, a Finite Element Analysis (FEA) analysis of Femur bone structure implant is done, to determine the relationships among the quantities that characterise the failure stresses. The fracture behavior of human bone during the action of unexpected cause of accidents is analyzed by the related works and numerical analysis on the model of particular bone is performed under various loading and boundary conditions. Stress fracture occurs predominantly in the weight-bearing bones of the lower leg and foot, with fewer incidents in the femur, pelvis, and lumbar spine. The combination of advanced numerical tools with the capacity of modern computers resulted in the creation of limitless possibilities towards the allowable stress and strain analysis in bone structures. The novel FEA method presented in this article can be used to identify the biomechanical phenomena occurring in femur bone structures as well as to validate the experimental results in the course of implants. It also enables the fast rehabilitation of fractured bone and shapes them optimally by taking into account of the limit tensile or compressive strengths exerted.
