Dynamic Fatigue Behavior of Hip Joint under Patient Specific Loadings

In the present work, a finite element model with standard Charnley’s implant of hip joint is considered for investigation under different patient-specific dynamic activities obtained in vivo. The application forces occurred due to human movement, which ultimately generates stress over prosthesis. Anatomical loading constraints are more clinically relevant than ISO standards. performance materials each suitable gait pattern analyzed using commercial code. A liner isotropic material Ti-6Al-4V and PMMA utilized an bone cement, respectively. However, cortical cancellous treated as non-isotropic nature. Clinically torque being used investigation. Additionally, Goodman, Solderberg, Gerber ASME elliptic fatigue theories were obtain life implant. most strenuous activity terms strain are, going downstairs followed by upstairs, walking, standing up sitting down, have been found good agreement safety factor every activity. expectancy was minimum 23 years motion. work exhibits greater relevance pre-surgical analysis before implanted
