Thin-walled structures are widely used in anti-collision devices for various vehicles due to their light weight and high energy absorption. Offset collision is a common scene traffic accidents. Because the commonly thin-walled do not consider this complex method, absorption effect of structure cannot meet requirements. In paper, C-shaped frame composed steel tubes proposed. The configuration st...

Thin-walled tubular structures are widely used in industries such as automotive, aerospace and military because of their lightweight excellent performance under different loading conditions. This study aimed to investigate the lateral crushing square aluminium tubes filled with cores (honeycomb, polyurethane foam mixed these two fillers). Different failure modes tested have been observed they p...

In this study, β-Ti3Au lattice structure was proposed for the first time in literature as a filling material to increase energy absorption performance of thin-walled tubes. context, performances conventional (i.e., BCC and FCC) filled tubes novel with were compared experimentally. hybrid, FCC hybrid structures produced by additive manufacturing technology using PA2200 powder crushed evaluated c...

Impact is one of very important subjects which always have been considered in mechanical science. Nature of impact is such that which makes its control a hard task. Therefore it is required to present the transfer of impact to other vulnerable part of a structure, when it is necessary, one of the best method of absorbing energy of impact, is by using Thin-walled tubes these tubes collapses unde...

Application of impact energy absorption systems in different industries is of special significance. Thin-walled tubes, due to their lightness, high energy absorption capacity, long crushing length and the high ratio of energy absorption to weight, have found ever-increasing application as one of the most effective energy absorption systems. In this research, through  carrying out experimental t...

in order to lighten the prestressed concrete solid members, nowadays, it is possible to make use of the advantage of hpc (fc'>60 mpa) as well as replacing the solid section with a psc thin-walled section for certain members such as circular and box columns. using the strength theory of aci, a numerical procedure along with a computer program was developed for the analysis of such sections ...
