Abstract

SHAPED CHARGEs defeat armors by means of high velocity jets formed by the collapse of a metallic liner as a result of the detonation of an explosive. The explosive formulation is an important factor influencing the properties of a SHAPED CHARGE. Explosive charges used in penetrating devices have usually high detonation velocity and high density. In this research, five compositions based on HTPB having different amount of aluminum (0 up to 40 percent by weight) were examined in a specific shape charge. After charging the samples by PBX materials, the PENETRATION experiments were carried out at 25 mm stand-off distance on mild steel targets. The results showed high PENETRATION capability of aluminum-free formulation. The jet resulted by detonation of this charge has a maximum depth and volume of PENETRATION in comparison with other PBXs. There is a nonlinear decrease in the PENETRATION of the SHAPED CHARGEs by adding aluminum in the formulation of explosives. The difference of results obtained via experimental and numerical simulation method (LS-DYNA) increases in compositions containing more percentage of ALUMINUM POWDER.
