چکیده

This research work studies energy absorption by aluminum open-sections with thin-walled square cross-section during the flattening process by numerical and experimental methods. For this purpose, two types of thin-walled open-sections with different geometries were produced by cutting process on thin-walled closed-section specimens that called types A and Q. Type A is a square open-section with straight lip length and type Q is a square open-section with triangular lip length. Firstly, closed and open-section specimens are laterally compressed between two rigid plates in the quasi-static condition. Then, numerical simulations of them are carried out by LS-DYNA software and the results are compared with the corresponding experimental results to calibrate the numerical simulations. Then, different types of thin-walled open sections are simulated by the LS-DYNA software and influences of specimen's geometry, lip length and loading velocity are investigated on energy absorption process through the numerical method

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
