| این مقاله به مطالعه تجربی، شبیهسازی عددی و مدلسازی ریاضی پاسخ دینامیکی ساختارهای دایرهای تکلایه و دولایه تحت بارگذاری دفعی موضعی میپردازد. در بخش تجربی، شش آزمایش روی پیکربندیهای دولایه ساختهشده از ورقهای مس-آلومینیوم (2 میلیمتر + 2 میلیمتر) در شرایط بارگذاری مختلف انجام شد. از نرمافزار تجاری آباکوس و یک زیر برنامه فرترن تعریفشده توسط کاربر برای تهیه مدل عددی استفاده شد. قانون ساختاری ویسکوپلاستیسیته جانسون-کوک و همچنین مدل آسیب آن در مدل عددی مورداستفاده قرار گرفت. مدلهای عددی با استفاده از آزمایشهای انجامشده در این مطالعه و دادههای موجود در ادبیات تحقیق، صحتسنجی شد. نشان داده شد که مدلهای عددی بهخوبی مکانیسمهای تغییر شکل ورق در طول فرآیند بارگذاری را ایجاد میکنند. علاوه بر این، یک مطالعه دقیق پارامتری روی ساختارهای فلزی دولایه ساختهشده از پنج لایهبندی مختلف ازجمله ساختارهای آلومینیوم-آلومینیوم، فولاد-فولاد، فولاد-آلومینیوم، مس-آلومینیوم و مس-فولاد انجام شد. دو شعاع مختلف برای ورق و چهار قطر مختلف برای خرج انفجاری در نظر گرفته شد. پس از انجام مطالعه پارامتریک، یک مدل تجربی مبتنی بر اعداد بدون بعد جدید برای پیشبینی حداکثر انحراف عرضی ساختارهای دولایه ارائه شد. توافق کلی بسیار خوبی بین نتایج شبیهسازی عددی و پیشبینیهای تجربی به دست آمد. | ||

| چکیده [English] | ||
| This paper dealing with an experimental study, numerical simulation, and mathematical modeling of the dynamic response of single-layered and double-layered circular plates under localized impulsive loading. In the experimental section, six experiments were conducted on double-layered configurations made of copper-aluminum plates (2mm+2mm) under different loading conditions. ABAQUS commercial software via a user-defined FORTRAN subroutine was used to develop a numerical model. The Johnson-Cook thermo-viscoplastic constitutive law, as well as the Johnson-Cook damage model, was used in the model. The numerical simulations were verified using the conducted experiments in this study and those in the literature. It has been shown that simulations correctly reproduce the deformation mechanisms of structures during the loading process. Furthermore, a rigorous parametric study was conducted on double-layered metallic plates made of five different layering configurations including aluminum-aluminum, steel-steel, steel-aluminum, copper-aluminum, and copper-steel plates. Two and four different plate radiuses and charge diameters were considered. After conducting the parametric study, an empirical model based on new dimensionless numbers was developed to predict the maximum transverse deflection of plates. Very good overall agreement was obtained between the results of numerical simulations and empirical predictions. | ||
