摘要: Abstract Quasi-static compressive testing of extruded aluminum alloy AA6061-T6 round and square cross-sectional tubular specimens was completed to investigate the crush characteristics these structural members under a cutting deformation mode by using specially designed tool. Results from experimental tests showed that tubes exhibited high force efficiencies (CFE) 0.95 0.81 respectively. In comparison, CFE experienced progressive folding global bending modes were observed be 0.66 0.20 respectively underwent found 0.22. An almost constant for in mode, while slight increase same mode. The occur primarily due conta...
