摘要在本研究中，提出了一种能够预测板凹痕试验输出的关系。结果表明，初始密度、凝聚相生成热、碳（C）、氮（N）、氧（O）的数量和组成分子量（MW）是准确预测有机炸药在1018冷轧钢板上产生的绝对凹痕深度所需的最重要参数。计算结果可用于预测炸药的爆压，并证明了炸药爆压与Gurney速度参数之间存在相关性。新的关联式被用来准确地估计几个C-H-N-O炸药成分。
ABSTRACT In the present study, a relationship is proposed that is capable of predicting the output of the plate dent test. It is shown that the initial density; condensed phase heat of formation; the number of carbon (C), nitrogen (N), oxygen (O); and the composition molecular weight (MW) are the most important parameters needed in order to accurately predict the absolute dent depth produced on 1018 cold-rolled steel by a detonating organic explosive. The estimated values can be used to predict the detonation pressure (P) of high explosives; furthermore, we show that a correlation exists between and the Gurney velocity parameter. The new correlation is used to accurately estimate for several C-H-N-O explosive compositions.
