Abstract

Abstract

The split Hopkinson pressure bars (SHPB) and drop-weight are used to study the effects of sintered and unsintered processes on the dynamic mechanical properties and reaction properties of reactive fragments under impact. The results show that the sintered reactive fragments have better mechanical properties. Both materials have obvious strain-rate effects, and the dynamic yield stress is 2.8–3.3 times of the static yield stress. The sintered reactive fragments are easier to react under the load of drop-weight, and the critical drop height of the reaction is 1.15 m. These results can effectively reflect the mechanical and reactive behavior of reactive fragments.
