Energy Dissipation Enhancement of Thin-Walled 6063 T5 Aluminium Tubes by Combining a Triggering Mechanism and Heat Treatment

It is necessary to reduce the weight of components while maintaining or improving their mechanical properties withstand dynamic loads in lightweight structures. In this study, heat treatment and a trigger mechanism were implemented for thin-walled tube aluminium increase energy absorption reducing peak crushing force. Different geometries locations proposed deformation controlled manner, combination with treatments. Experimental designs each performed, tested by quasi-static crushing. Data obtained from experiments used calculate indicators that compared without analyse performance. By comparing tubes modification, best design variables identified. was determined 160 mm upper side, 250 mm2 area rectangular shape reduced force 22.03% increased 37.76%. For treatment, optimal heating furnace at 175 ?C 1 h cooling water 70 during 10 min only soaking half its length. This 19.02% 15.08%. When these mechanisms combined on single tube, 21.63%, 42.53%.
