摘要

The significance of bio-implants at the hip region cannot be overstated, as they play a crucial role in restoring mobility and improving the quality of life for individuals with hip-related issues. Earlier Co-Cr, SS alloys were used as implant materials, but cytotoxicity and elastic modulus differences affect the longevity and performance of hip joints resulting in stress shielding. Ti alloys have emerged as the most suitable material because of their excellent biocompatibility, corrosion resistance, and favourable mechanical properties, including a suitable Young’s modulus for mimicking natural bone. The primary objective of this research is to model hip implants made from different materials (Cobalt-Chromium, Stainless Steel, Ti-6Al-4 V, and Ti-25Nb-11Sn), and compare their deformation behaviour using ABAQUS software. This finite element analysis software allows for the precise modelling of complex structures, enabling a thorough investigation of the mechanical response of different materials under varying conditions. The study involves the creation of detailed hip implant models, encompassing various designs, components, and assemblies. Additionally, the project defines and applies realistic boundary conditions and loads to simulate actual physiological conditions experienced by hip implants during daily activities. By employing ABAQUS, the study aims to determine the Von Mises stress distribution in each material, providing valuable insights into the structural performance and potential areas of improvement for hip prostheses.
