Abstract: (6331 Views)
Orthopedic implants are one of the most reliable methods for bone injuries treatment. An important issue, which must be considered in the design of orthopedic implants, is that the Young's modulus of implants should be near to the host bone to prevent complications such as stress shielding. Porous implants are considered as one of the new and effective methods for this issue and recent technologies such as metal 3D printing made it possible to manufacture different porous structures with various geometries, which could be used to reach the goal. Porous geometries are used to approaching the elastic modulus of implantation with a porous structure to the bone. Mechanical properties of Diamond porous structure have been investigated in this study and an equation for obtaining the modulus of elasticity is presented in terms of the geometric parameters of this structure. Based on the results, the error between finite element analysis and experimental data is between 3.64% and 18.51% and it has been shown that the Young's modulus obtained from finite element method is more in line with the existing experimental data than the analytical results; by the increase of relative density, the error would be decreased. Furthermore, in the relative density between 0.06 and 0.16, the Young's modulus of titanium Diamond structure would be the same as bone Young’s modulus, which is an effective feature in design of orthopedic implants.
