Abstract AR
تم اختبار وجود ترابط بين m, A ، معلمات باريس نظريا بالنسبة للمواد الهشة مثل سيراميك الألومينا (Al2O3) باختلاف الحجم الحبيبي، و التحقق من وجود دالة أسية توائم أغلب القيم التجريبية لمخطط سرعة نمو الشق مع عامل شدة الإجهاد.
و تم تطبيق نظرية معدل التغير لنمو الشق على نماذج من سيراميك الألومينا في المنطقة I و تم تخمين معلمات نظرية معدل التغير من معلمات الدالة الأسية.
Abstract EN
The question about the existence of correlation between the parameters A and m of the Paris function is re-examined theoretically for brittle material such as alumina ceramic (Al2O3) with different grain size.
Investigation about existence of the exponential function which fit a good approximation to the majority of experimental data of crack velocity versus stress intensity factor diagram.
The rate theory of crack growth was applied for data of alumina ceramics samples in region I and making use of the values of the exponential function parameters the crack growth rate theory parameters were estimated.
