Low speed impact properties of 5052 aluminum alloy plate

Abstract

The impact failure experiment of aluminum plate is the main method to study the failure mechanism of aluminum plate under the condition of rapid deformation. In this paper, the impact experiment of 5052 aluminum alloy plate with different impact energy combination were carried out to study the low speed impact behavior of 5052 aluminum alloy plate under various conditions. The effect of different parameters on the impact property of 5052 aluminum alloy plate during impact process were explored by experiments and numerical simulations.The results show that under the same energy, the combined impact of the punch with lower mass and higher impact velocity (i.e., smaller momentum) causes greater damage to the 5052 aluminum alloy plate. The impact load, energy absorption and damage form are closely related to impact energy and punch momentum.The dynamic relations of energy, displacement, velocity and time during the collision process obtained by the actual parameter experiment are basically consistent with the numerical simulation results, which verifies the reliability of the numerical simulation method.
