Abstract AR
السلوك اللزج-المرن للمواد المركبة مثل البوليستر المدعمة بطبقة من الألياف الزجاجية عشوائية التوزيع، و صف نسبة (Poisson) في معادلة جديدة للزمن و الإجهاد.
أجهاد الاسترخاء تم حسابه عمليا لوصف السلوك اللزج-المرن اللاخطي في المواد المركبة.
النتائج أظهرت أن نسبة (Poisson's Ratio) تزداد بنسبة تقريبية 16 % نتيجة لزيارة الإجهاد من 8.
239 MPa-6.
877MPa عند درجة حرارة ثابتة 30 درجة مئوية.
كذلك يتناقص مع ازدياد الزمن.
البحث الحالي يثبت انه ليس من الضروري تتبع خطوات نظرية اللزوجة-المرونة لوصف السلوك اللزج-المرن.
Abstract EN
In viscoelastic behavior of composite material, such as those made of thermo-set polyester and one layer random fiber glass, the Poisson’s ratio is described in new function of time and stress.
The relaxation stress is obtained experimentally to describe the non-linear viscoelastic behavior in composite material.
The results show that, Poisson’s ratio increases with an approximate rate of 16 % as a result of the increasing stress from 6.877 MPa to 8.239 MPa and decreases with increasing the time at constant temperature 30 Co.
The investigation demonstrated that such time dependence is not a necessary consequence of the theory of viscoelasticity to describe viscoelasticity behave.
