Abstract :

The Design And Structural Analysis Of An Ankle Joint Implant Were Carried Out Using CATIA For Modeling And ANSYS For Finite Element Analysis, Focusing On Static And Modal Behavior Under Physiological Loads Of 2500 N And 3500 N. A Comparative Evaluation Of Implant Materials—CoCrMo, Ti-6Al-7Nb, Ti-13Nb-13Zr, And SS 316—was Performed To Assess Von Mises Stress, Shear Stress, Deformation, And Natural Frequencies. Results Indicate A Linear Increase In Von Mises And Shear Stresses With Increasing Load For All Materials. However, CoCrMo Consistently Demonstrated The Lowest Von Mises Stress (71.581–90.927 MPa), Lowest Shear Stress (41.328–52.483 MPa), Minimal Deformation (0.161 Mm), And The Highest Natural Frequencies, Reflecting Superior Stiffness And Vibration Resistance. Titanium Alloys Exhibited Moderate Mechanical Performance, While SS 316 Showed Significantly Higher Deformation (up To 3.642 Mm) And Reduced Structural Stability. The Findings Confirm That CoCrMo Offers Exceptional Mechanical Stability, Stress Resistance, And Durability, Making It The Most Suitable Material For Ankle Joint Implants Subjected To High Biomechanical Loads And Demanding Physiological Conditions.
