Experimental and numerical analysis of the aluminum alloy AW5005 behavior subjected to tension and perforation under dynamic loading
der impact loading. The work is focused on tensile tests and the process of perforation of
aluminum alloy AW5005 sheets. Experimental, analytical and numerical investigations are
carried out to analyse in details the perforation process. Based on these approaches, ballistic
properties of the structure impacted by a conical nose shape projectile are studied. Different
failure criteria are discussed, coupling numerical and experimental analyses for a wide range
of strain rates. Optimization method functions are used to identify the parameters of the
failure criteria. Finally, good correlation is obtained between the numerical and experimental
results for both tension and perforation tests.
