The Impact

The capable of structures to absorb large amount energy are great interest in an effort to reduce the impact of collision. In this research, an experimental investigation was carried out to study the crashworthiness parameter and behavior of pultruded fiber E-glass/polyester composite tubes subjected to oblique load during progressive collapses. Two different pultruded wall thicknesses of 6 mm and 9 mm tubes were used and four load angles of 0˚, 5˚, 10˚ and 15˚ were selected to study their effect on crushing behaviors and collapse modes. All specimens were chamfer 45˚ on top end as purpose to work as a collapse trigger mechanism. The result showed that increasing the angle of loading will decrease the energy absorption of the structures. Pultruded tubes with 9 mm thick wall absorb more energy compare to 6 mm thick walls.
