Biomechanical Analysis of a Femur Bone

Abstract

In this paper, a CAD model of human femur bone was generated and was analysed which is useful for medical industry for implementing the correct size and correct plate that can withstand the stresses developed by the user. The purpose of the work is to find a suitable material which can withstand the maximum stress made by the user. In this paper internal fixation is analysed. The image of femur bone is generated by using the 3D slicer where CT scan data in form of DICOM files is sent to the software to generate 3D model and the Bone plate, screws are modelled by using SolidWorks, the dimensions of the plate and screws are taken according to the generated femur bone. The function of the bone was analyzed for four different materials i.e. Nylon, PMMA, SS316L, TI-6Al-4V by using Ansys software and when the body is physically active. Total deformation and von-misses stress analysis help to choose the material which can withstand the max stress under different activities.
