Buckling and Failure Analysis of Bones in Hip Joint

Abstract

Free body diagram is drawn to compute the various forces and torques acting on hip joint. The FEA models for hip joint and acetabular cup are drawn with the help of CT Scan reports. The stress distribution and deformations are then obtained by using finite element analysis. Contact stresses, contact area radius and maximum pressure are obtained. Modeling of the hip joint and acetabular cup was done and stress distribution was also determined. Since the thigh bone is slender, it was analyzed both manually and through software for buckling. This analysis is performed in order to predict the failure of bones in the hip joint.

İnsan Femur Modeli Üzerinde Flambaj Etkisinin Sonlu Elemanlar Metodu Kullanılarak Biyomekanik Olarak İncelenmesi

“…Biyomekanik disiplin, tespit ve teşhis, cerrahi uygulamalar, ortotik protez uygulamaları, tedavi öncesi ve sonrası rehabilitasyon uygulamaları ve cerrahi öncesi planlama gibi birçok süreçte çok önemlidir. Madeti ve diğ [14] tarafından hertz temas gerilmesi ve burkulma analizi ele alınmıştır. Eksantrik yöntem burkulma analizi kullanılarak kritik yük elde edilmiştir.…”
