Numerical analysis on the ignition mechanism of explosive in drop-weight test
炸药落锤试验点火机理的数值分析
Based on the data of Drop-weight test of various kinds of specimens with different thickness, it could be concluded that the value of T_(NDT) is not only dependent on the materials but also the thickness of the specimen.
以3种供应状态、5种钢材、6型试样的落锤试验数据说明钢材的无塑性转变温度TNDT不仅与材料有关,而且与试样厚度有关,二者的关系可用函数式TNDT=At-m+B表示,式中的A、B、m是与材料有关的参数。
