Damage evolution determined by material mass distribution of reactive material-metal composite jet impacting multi-spaced plates

The reactive material-metal composite jet (RMM-CJ), exhibiting a dual penetration-enhancement effect is of growing concern. In the present study, the composite jets of reactive material-copper (RM–Cu), reactive material-titanium (RM–Ti), and reactive material-aluminum (RM–Al) impacting multi-spaced plates were studied experimentally and numerically. A comprehensive analysis of the damage effects was conducted based on experimental and simulation results. The results show that the damage area of each layer of plate is closely related to the mass distribution of reactive material. The relationship of the mass of each layer of reactive material with time is given, and the deflagration gain is quantified. The research results provide a useful reference for the design and optimization of reactive material-metal composite liners.
