STUDY REGARDING PROPAGATION AND ATTENUATION OF A SHOCKWAVE AT THE IMPACT WITH A DURALUMINUM TARGET

This paper presents the analytical study of shock waves resulting from the impact of a cylindrical projectile on a static target. In this analytical study the materials are considered under hydrodynamic treatment (without elastic limit). The analytical study is complemented by numerical simulations using the ABAQUS code. Firstly, the corresponding configuration for various impedance ratios of the projectile and target material has been analyzed, subsequently the unit ratio material Al2024 (duralumin) being chosen. Thus the case where a projectile hits a target of the same material, namely duralumin is analysed. Shock wave propagation equations, reflection and attenuation of the shock wave in the projectile and target were determined. It is of interest to determine the distance traveled by the shock wave before attenuation, both in the target and the projectile. We noticed that the experimental results obtained with Taylor's cannon are consistent with those obtained from simulations with the ABAQUS code.
