Abstract
The damage effects of reactive material jet against steel targets were researched by the combination of static explosive experiments and theoretical analysis. The experimental results show that, compared with the traditional metal jet, the diameter of the penetration hole formed by reactive material jet in steel targets was much larger together with stronger blast-induced crack effects, while the penetration depth shows a significant decrease. Based on the quasi-steady incompressible fluid theory and modified Bernoulli equation, a theoretical model for analyzing the penetration and blast combined damage effects was developed to consider the self-delay imitation time of reactive material jet. As such, a theoretical explanation from the perspective of damage mechanism about the combined damage effects was presented by this analytical model.
