Güçlendirilmiş Dört Folyo Kesitli Al6061 Tüplerinin Eksenel ve Eğik Darbe Koşulları Altında Çarpışma Dayanıklılık Performansı

This study presents the crashworthiness performance of Al6061 tubes with stiffened quatrefoil sections under axial and oblique impact conditions. Influences of different types of stiffeners through the depth of tubes in the design of a quatrefoil sectional crash absorber structure are investigated, numerically. Four types of stiffener patterns are considered under oblique impact angles of 0º, 10º, 20º, and 30º measured from the horizontal axis....
