There are two basic approaches to suppression of sympathetic detonation. Minimizing the shock sensitivity of the explosive to long duration pressure will obviously reduce interround separation distances. However, given that the explosive sensitivity is fixed, then much can be gained through the use of simple barriers placed between the rounds. We have devised calculational methods for predicting shock transmission experimental methods have been developed to characterize explosive shock sensitivity and observe the response of acceptors to barriers. We have shown that both EAK and tritonal can be initiated to detonation with relatively low pressure shocks of long durations. And we have shown that to be an effective barrier between the donor and acceptor, the material must attenuate shock and deflect fragments. Future actions will concentrate on refining the design of barriers to minimize weight, volume, and cost.
