Abstract: In this paper, to better understand the spall properties of 6061 Al-Alloy, a combined analysis of experimental and numerical simulation study is conducted. A series of plate impact experiments loaded by gas gun have been performed at a range of velocities required to cause spall planes to grow in these variously heat-treated 6061 Al-Alloy specimens. Two different methods are employed. A commercial manganin stress gauge is sandwiched between the specimens and a buffer material with lower shock impedance (usually PMMA) which is used to determine the stress profiles; without the buffer material, target is well recovered by avoiding any unwanted impact, then the collected specimen is examined under a microscope for charactering fracture damage. The spall strength and the process of spallation are presented from the experimental results. The finite element code LS-DNYA is used to simulate the plate impact testing. The damage distribution and its development in the specimens are given from the numerical results, which is coincided with the experimental results. © 2009 SPIE.
