Abstract: Finite element analysis (FEA) has been increasingly used in biomedical engineering to simulate prosthetic knee implants. One of the most common challenges when modeling knee implants are properly characterizing the physical properties of cellular materials like cancellous and cortical bones. For the mechanical modeling of cancellous and cortical bones, the material homogenization techniques became the most efficient method in characterizing the mechanical properties. Most of the homogenization strategies make use of the application of the representative volume element (RVE) for simulating the effective material behavior. The objective of this study is to apply FEA to make a deep comparison between two implant tray materials (Co-Cr-Mo and Ti-Al) at the tibia-implant interface under the constant loading condition with the help of Micromechanics RVE plugin in Abaqus/CAE. The RVE technique allows the characterization of the mechanical properties of the cancellous and cortical bones with distinct constituents and microstructures, thereby making the relative implant comparison possible.
