ABSTRACT
The objective of this chapter is to perform the biomedical study of femur bone using FEA. For this purpose, a literature review from 1980 to 2021 was performed. In previous studies, researchers performed only modal and structural analyses of femur bone at different boundary conditions, but in the present study, structural, modal, scale-up, scale-down, and crack analyses and crack healing using plates are performed. Modeling of femur bone was done using SolidWorks considering the drawing dimensions of CT scanned femur bone, and this model of femur bone was also scaled down (90%) and scale up (110%) of original bone dimension to consider anthropometrics factor. The first ten natural frequencies of the femur bone at different conditions were simulated. A structural analysis was performed, and mode shapes at different natural frequencies were analyzed for excitation and fracture detection. In this chapter, bone crack and its healing using support plate and screws were studied. Further structural and modal analyses were performed for varying the support plate material, and the strength analysis of plate was performed. In order to enhance the healing and reduce loss in bone mineral density, some improved materials have been found for surgical implants, which give scope for future study.
