“…Different modes of crushing have been identified, such as splaying and fragmentation modes [20]. The crushing modes and consequently the specific energy absorption are dependent on multiple parameters such as the tube geometry [28][29][30][31][32], fiber type [33,34] and architecture [31,32], matrix resin [35], testing speed [32,36,37], temperature [38], trigger [39,40] and surface treatment [41]. Recently, Mahdi and Sebaey [42] have reported that radial reinforcements improve crashworthiness capabilities.…”

International audienceBraided composites tubes have been reported to have a great potential in crash energy absorption applications. However, previous works were limited to thermoset braided composite tubes. In this study, we are interest in the crash energy absorption performance of 2.5D braided thermoplastic composite tubes. The sensitivity to materials, fiber orientation and geometry was investigated. Three crushing modes have observed. The splaying and progressive folding were reported for glass/polypropylene tubes and fragmentation mode was observed carbon/polyamide tubes. The last mode has the highest specific energy absorption of 61 kJ/kg. The progressive folding mode has higher specific energy absorption (36 kJ/kg) than the splaying mode. Moreover, the specific energy absorption increases with increasing braiding angle and decreasing length-to-diameter ratio, for glass/polypropylene tubes. On the opposite, the specific energy absorption deceases with braiding angle for carbon/polyamide tubes

“…When energy-absorbing devices are considered, there are three classification groups; each one relies either on material deformation, extrusion or friction [3]. The impacting of cylindrical tubes can normally be evaluated in many ways ranging from quasi-static testing [4], dynamic testing [5] and impact testing [6].…”

One of the important objectives in this research is investigating the behavior on the cylindrical tube structure via computer simulations. When a thin cylindrical structure is experienced an impact loading, the crushing process on impact can only be observed by a high speed camera. Recording the stress and strain data is also not possible experimentally. A numerical approach implementing finite element method with a dynamic-explicit code is an effective solution to observe the crushing process. A thin cylindrical structure found in aluminium can is modeled. A finite element impact simulation is then performed to observe the crushing process sequence and the stress and strain development history on axial impact employing IMPACT application program. An experimental of thin cylindrical structure on axial impact is conducted. The final crushing pattern after the impact is then compared with that from simulation. The result shows that final crushing pattern is in a good agreement with that shown in experiment. The stress and strain histories can be observed from the simulation.

“…It has been proved that the Mg alloy sandwich has ultra-light weight as well as better specific strength and rigidity than that of aluminum alloy. One of the main drawbacks of sandwich structure is its low resistance to impact damage and the extent to which the strength of the structure is reduced under compressive loading [5,6]. At present, the energy absorption properties under impact as well as the vibration response of magnesium alloy honeycomb sandwich are still open to designers.…”

This paper describes the results of an experimental investigation on the drop off impact test on a range of sandwich panels. The magnesium alloy sandwich panels were fabricated with rolled sheets at different thickness by pressing and bonding method. Out-plane compression test was employed to obtain its basic deformation-force behavior. The impact experiments were carried out in which a steel cylinder was dropped off at various height levels, ranging from 0.5m to 1.5 cm to impact the panel. A high speed camera was employed to take pictures at 20 thousand frames per second and the low-velocity impact response on the sandwich panels is recorded with a dynamic force senor under the panel simultaneously. The shock response with time and the impact absorption energy were analyzed and compared. The results of this study proved that the magnesium alloy honeycomb sandwich panels have good impact energy absorption performance.
