Deformation behavior of aluminum alloy tubes during wire-explosion impact forming

Abstract Wire-explosion impact forming (WEIF) is a process based on coupled effect of gaseous, liquid, and solid media, the experimental work alone not sufficient to properly show this complex process. To understand plastic deformation behavior workpiece under action shockwave load, WEIF AA5052 tubes were simulated in LS-DYNA by considering fluid/structure interactions. Then, stress, displacement, velocity, thickness during quantitatively analyzed, generation propagation shock waves demonstrated. Finally, numerical simulation results effectively verified results.
