Design of Titanium Alloy Femoral Stem Cellular Structure for Stress Shielding and Stem Stability: Computational Analysis

The main objective of this study is to design titanium alloy femoral stems with cubic porous structures that will be able reduce stress shielding and promote stem stability. These structure designs were introduced into as homogeneous functionally graded structures. First, the cellular simulated under compressive loading measure yield modulus elasticity for various porosity ranges. Based on selected range, fifteen different arrangements radial geometrical (FG) developed average porosities 30, 50, 70% respectively. Finite element models physiological loads presenting three walking speeds (1, 3, 5 km/h), where human body weight was assumed. Stresses at bone Gruen zones measured check percentage transfer each compared bulk stem. Several FG shortlisted further investigation candidates hip implants.
