Abstract AR
تم دراسة سلوك سبيكة الألمنيوم AA7349 عند تداخل الزحف و الكلال الثابت و التراكمي باستخدام منظومة كهربائية تم تصميها و ذلك لتحقيق تداخل الزحف و الكلال عند مستويات أجهاد مختلفة و درجات حرارة مختلفة.
و قد تعرضت عينة الألمنيوم AA7349 إلى اختبارات تداخل الزحف و الكلال الثابت و المتغير تحت سيطرة الإجهاد و الانحناء الدوار بنسبة إجهاد R = -1.
تم دراسة نتائج تداخل الزحف و الكلال باستخدام قاعدة ماينر و تم مقارنتها مع النموذج المقترح و الطريقة العملية.
و قد تبين أن قانون ماينر و النموذج المقترح أعطت نتائج معقولة و كانت بتوافق جيد مع النتائج العملية.
Abstract EN
In this present work, the behavior of AA7349 aluminum alloy under constant and cumulative creep-fatigue interaction has been studied by using an electrical system designed and built in order to investigate creep-fatigue interaction at different stress levels and temperatures.
An hour-glass shaped specimen of AA7349 aluminum alloy has been subjected to a constant and variable creep-fatigue tests performed under rotating bending loads and stress control at stress ratio R=-1.
The results of the creep –fatigue life have been studied by Miner rule and compared with the proposed and experimental methods.
It was shown that the Miner rule and proposed model give reasonable results and they are in a good agreement with the experimental fatigue lifetimes
