چکیده
امروزه استفاده از ساختارهای ساندویچی به دلیل خواص مناسبی که دارند به‌طور روزافزون در حال افزایش است. پانل های ساندویچی متشکل از صفحات رویه و هسته فوم فلزی به‌طور گسترده‌ای برای مقاومت در برابر ضربه با سرعت‌پایین استفاده می شوند. در این تحقیق سعی شده است تا بامطالعه رفتار فوم‌ آلومینیومی و استفاده از آن‌ در سه نوع ساختار ساندویچی با هسته‌های موجدار مستطیلی، ذوزنقه‌ای و مثلثی خواص جذب انرژی آن‌ها را تحت ضربه با سرعت‌پایین به‌صورت تجربی و عددی موردبررسی قرار گیرد. این آزمایش‌ها با استفاده از یک ضربه‌زننده سر تخت بر روی پانل‌های ساندویچی با هسته موجدار با و بدون فوم آلومینیومی انجام شده است. همچنین با استفاده از نرم‌افزار آباکوس فرآیند مدل‌سازی و تحلیل نمونه‌‌ها صورت گرفته است. آزمون تجربی ضربه با سرعت پایین نیز برای صحت سنجی نتایج شبیه‌سازی توسط دستگاه سقوط وزنه انجام شده است. حالت‌های تغییر شکل، نمودارهای جذب انرژی و سهم جذب انرژی هر جزء مورد بحث قرار گرفته است. نتایج نشان‌دهنده آن است که استفاده از فوم آلومینیومی به صورت قابل توجهی سبب افزایش ظرفیت و بهبود روند جذب انرژی سازه شده است و از نفوذ ضربه‌زننده در پانل جلوگیری کرده است. همچنین نتایج نشان داد که هسته‌های موجدار مستطیلی، ذوزنقه‌ای و مثلثی رفتار متفاوتی در جذب انرژی و جلوگیری از نفوذ ضربه‌زننده داشتند؛ بطوریکه هسته موجدار مستطیلی روند جذب بهتر و سریع‌تری داشت و از نفوذ ضربه-زننده به داخل پانل بیشتر از دو هسته موجدار دیگر جلوگیری به عمل آورد.

چکیده English

Today, the use of sandwich structures is increasing due to their good properties. sandwich panels consisting of face sheets and metal foam core are widely used for low velocity impact resistance. In this research, by studying the behavior of aluminum foam and using it in three type of sandwich structures with rectangular, trapezoidal and triangular corrugated cores, we have tried to experimentally and numerically investigate their energy absorption properties under low velocity impact. These tests were performed using a flat head impactor on corrugated core sandwich panels with and without aluminum foam. Also the process of modeling and analysis of samples has been done using Abacus software. Experimental test of low velocity impact were also performed to verify the simulation results by a drop weight device. Failure modes, energy absorption diagrams and energy absorption contribution of each component are discussed. The results show that the use of aluminum foam significantly increases the capacity and improves the process of energy absorption of the structure and prevents the penetration of impactor on the panel. Also, the results show that rectangular, trapezoidal and triangular corrugated cores have different behavior in absorbing energy and preventing impactor penetration; So that the rectangular corrugated core has a better and faster absorption process and prevents the penetration of the impactor into the panel more than the other two corrugated cores.
