Bio-mechanical design and analysis of femur bone

Abstract

Abstract The objective of this research article is to perform the detailed study of femur bone by using finite element analysis method on ANSYS software. For this purpose literature review studied from 1980 to 2019. In previous studies the researcher did modal and structural analysis of femur bone at different boundary conditions. In this research modelling of femur bone was done on solid works taking the drawing dimensions of CT scanned femur bone and this model of femur bone was also scaled to 90% to 110% to because of anthropometrics. Natural frequencies of different size femur bone studied at different boundary conditions. Structural analysis has been performed and mode shapes at different natural frequencies studied. In this project the fracture has been identified and for healing the support plate and screws designed and fixed to fractured bone. Further structural and modal analysis done for varying the support plate material and strength analysis was performed. In order to enhance better healing and reducing loss in bone mineral density some improved materials has been found for surgical implants give scope for future study.
