| چکیده | ||
| یک مطالعه عددی پیشرفته حاوی تعامل سیال و جامد بر اساس روش مرز غوطهور برای بررسی تأثیر فشار پیشانفجار و بازه زمانی تغییرشکل پلاستیک ورقهای مثلثی نازک تحت انفجار گازی انجام میشود. سایر اهداف شبیهسازی عددی مانند محاسبه تغییرشکل و کانتور تنش ماده در نرخ کرنش زیاد بر اساس مدل مادی جانسون-کوک وابسته به نرخ کرنش به دست میآیند. شبیهسازی بر اساس مدلسازی انفجار با سینتیک واکنش شیمیایی و بهره بردن از حلگر CESE برای گسترش انفجار انجام میشود. روش مرز غوطهور برای شبیهسازی حرکت سطح میانی بین گاز منفجرشده و ورق تغییرشکل یافته از محاسبه پخششدگی فشار سیال بر سطح ورق استفاده میکند. ابزار عددی با بهره بردن از معادلات اویلری واکنش چند جزئی و معادله لاگرانژی ورق، پخششدگی فشار و پارامترهای انفجار گازی را به تغییرشکل ماکروسکوپیک ورق مرتبط میکند. روش عددی بهعنوان یک ابزار مناسب در محاسبه پروفیل تغییرشکل ورق مثلثی مبین کاهش تغییرشکل با اندازه کوچکتر سطح بدون پوشش ورق است. | ||

| چکیده [English] | ||
| An elaborate numerical study with a validated LS-DYNA® immersed boundary method fluid-solid interaction code is used to characterize the influence of pre-detonation pressure and time duration on plastic deformation of thin steel triangular plates subjected to gaseous detonation. Other objectives of this numerical simulation such as estimation of deflection and stress contour of material at high strain rate are derived based on a strain-rate dependent Johnson-Cook material model. Simulation relies on the modeling of detonation by chemical reaction kinetic and its propagation by Conservative Element Solution Element (CESE) solver. Immersed boundary method is used to simulate the interface motion between the detonating gas and the deforming plate to facilitate the assessment of fluid pressure distribution on the plate surface. The numerical tool relates the pressure distribution and gaseous detonation parameters to the plate macroscopic deformation by employing multi-species reactive Euler’s equations for the gas and Lagrangian equation for plate. Numerical method as an appropriate tool in the evaluation of the deflection profile of the triangular plate shows that deflection decreases by the smaller size of the exposed area of the plate. | ||
