| در طراحی سازههای مختلف، مهماست که آنها توانایی تحمل بارهای مختلف را داشته باشند. دراین راستا، ساندویچپنلها بهدلیل سبکی و جذب بار مطلوب، مورد توجه قرار گرفتهاند. با توجه بهاینکه ضربه ناشی از انفجار میتواند بر سلامت انسان تأثیر بگذارد، بررسی رفتار ساندویچپنلها تحت این بارگذاری مهم است. در این تحقیق، ساندویچپنلهای لانهزنبوری با سلولهای هسته متفاوت، تحت بارگذاریهای انفجاری متقارن همزمان قرارگرفته و تأثیر تغییر وزن و فاصلهی بارها، بر تغییرشکل ارزیابی شده است. باتوجه بههزینه بالای انجام آزمایشهای تجربی، از روش عددی توسط نرمافزار المان محدود الاسداینا استفاده شد. پس از طراحی و اعتبارسنجی با دادههای تجربی موجود در ادبیات، مقادیر 0/5، 1 و 2کیلوگرم تیانتی در یک و دونقطه(0/25×2، 0/5×2 و 1×2کیلوگرم) در فاصله 10سانتیمتری ساندویچپنل با ساختارهای سلولی هسته مربع، دایره و هشتضلعی منفجر شده و تغییرشکل آنها ارزیابی شد. بهمنظور بررسی تأثیر فاصله بارهای انفجاری بر تغییرشکل در بارگذاری دونقطهای، این بارها در فواصل 8، 10 و 12سانتیمتری از یکدیگر قرار داده شده و میزان تغییرشکل ساندویچپنلها با سلولهای مختلف، با انفجار تکنقطهای مقایسه شدهاست. برطبق مطالعات انجام شده، بهترین ساختار برای جذب بارهای انفجاری، هشتضلعی ارزیابی شده، بهگونهایکه بهترتیب در انفجارهای تکنقطهای و دونقطهای، در بهترین حالت 14/1 و 12/2میلیمتر، جابجایی کمتر داشته است. | ||

| چکیده [English] | ||
| In the design of structures, it is important that they have the ability to withstand loads. Sandwich panels have received attention due to their lightweight and good absorption. In this research, honeycomb sandwich panels with different core topologies were subjected to simultaneous impulsive loading, and the effect of the amount of loads and the distance between charges on the deformation was evaluated. Due to the high cost of conducting the experimental test, the finite element software has been employed. After validating with the experimental data, the values of 0.5, 1, and 2 kg of selected charge in single and two-point loading at the sandwich panels with square, circular, and octagonal core topologies have been affected and the deformation of sandwich panels has been evaluated. In order to investigate the effect of the distance of charges from each other on the deformation, these are placed at 8, 10, and 12 cm from each other. Then, the amount of deflection of sandwich panels with single-point loading has been compared. According to the investigations, the best topology for absorbing loads is octagonal, so it has less displacement in single and two-point loading in the best case of 14.1 and 12.2 mm, respectively. | ||
