Dynamic response of aluminium sheet 2024-T3 subjected to close-range shock wave: experimental and numerical studies

Popis výsledku v původním jazyce

This present study investigates experimentally and numerically the behaviour of 1 mm thick aluminium 2024-T3 alloy sheets from near field shock waves. A comparison and examination are undertaken with respect to global deformation and plastic damage formation from two different stand-off distances of 4 mm and 50 mm that were exposed to a constant charged mass. A 4-cable instrumented pendulum blast set-up was used to carry out and monitor the blast test. The results of the blast test were subsequently used to simulate the pressure history for different stand-off distances. The simulation involved implementing a user subroutine in ABAQUS/Explicit solver to model non-uniform pressure fields for use in finite element simulation. The results provided a strong alignment of the numerical method when compared with the experimental data. The main outcome of this study is to show the significant effect of the changing damage from highly localised perforation to global deformation when the stand-off distance is changed from 4 mm to 50 mm.
