摘要：

In this paper we describe a new small-scale test, requiring small quantities of energetic material, designed using our CHARM ignition and growth routine in the DYNA2D hydrocode. The new test is a modified gap test and uses detonating nitromethane to provide dynamic confinement (instead of a thick metal case) whilst exposing the sample to a long duration shock wave. This arrangement allows less reactive materials that are below their critical diameter, more time to react. We present details of the modelling of the test together with some preliminary experiments to demonstrate the potential of the new test method.
