Abstract To improve the crashworthiness and energy absorption of thin-walled tube structures, a bionic was designed based on structural characteristics antler osteon principle bionics had same inner outer diameters gradient thickness as osteon. A nonlinear finite element method is used to simulate with equal variation (EGTTS) under axial oblique loads. The EGTTS-7 (Egtts 7 layers) evaluated usi...

Offshore structures are exposed to risks of vessel collisions and impacts from dropped objects. Tubular members extensively used in offshore construction, thus, there is scope investigate their crashworthiness behaviour. Aluminium, glass fibre reinforced polymer (GFRP) hybrid aluminium/GFRP circular tube specimens were fabricated then tested under quasi-static dynamic axial loading conditions. ...

Porous aluminum (Al) composites are lightweight and high-strength materials composing of Al as a matrix material with some strengthening reinforcements pore-forming agents that result in the formation new superior physical properties energy absorption capacities. This work gives an overview porous Al-foams developed thus far, including foaming space holders, their properties, production techniq...

The National Highway Traffic Safety Administration’s (NHTSA) Vehicle Safety Rulemaking and Research Priority Plan 2009 – 2011 describes the projects the agency plans to work on in the rulemaking and research areas in those calendar years. Specific programs identified in the plan included research to improve vehicle safety for rear seat occupants, children, and older people. In support of the pr...
