Abstract AR
في ھذا البحث یتم دراسة و تحلیل آلیة الفشل في الطرف الاصطناعي غیر مفصلي (SACH) في منطقة البرغي, أجریت اختبارات الخواص المیكانیكیة و الكلال للمادة المصنع منھا البرغي, و ھي المنطقة التي یحدث فیھا الفشل و إدخال هذه الخواص لبرنامج التحلیل الھندسي (Ansys) لحساب عامل الأمان للكلال و الإجهاد المكافئ (Von-Mises).
النتائج أظهرت أن أعظم إجهاد مكافئ و أقل عامل أمان للكلال ظھر في منطقة البرغي عن المنطقة الفاصلة بین Adapter و القدم عند السن و في حالة السكون, كان تأثير رد فعل الأرض عن طور toe off أكبر مما علیه عند طور heel strike.
Abstract EN
This paper presents is the study and analysis of failure mechanism of non-articular prosthetic foot (SACH) in the region (Bolt Adapter).
The tests of mechanical properties and fatigue behavior were carried for material of which the bolt manufacture from it is a region where the failure occurs out and inserted of these properties to the program of engineering analysis (Ansys) to calculate the safety factor of fatigue and stress equivalent (Von-Mises).The results that both, showed the maximum equivalent stress and the minimum safety factor of fatigue are located in bolt at interface region between the adapter and the foot at notch, however, in static case, the effect was on the ground reaction force at toe off phase more than heel strike phase.
