摘要
本文介绍了利用粘结拉伸法和球形夹具拉伸法测定JO-9159在不同的应变速率、不同温度及不同加载历程下的拉伸应力-应变曲线,同时给出TNT/RDX(40/60)在不同横梁速度及不同温度下的拉伸应力-应变曲线。根据塑性力学理论,对所测出的各条曲线的数据通过拟合处理,导出含有一定物理意义的数学模型。
The tensile stress-strain curves of explosive JO-9159 were determined by using the method of adherence-tension and globe-grip tension at different rate,tempera- ture and loading course.The tensile stress-strain curves of TNT/RDX 40/60 at differ- ent crosshead rate and temperature were given as well.The data from every curve were fitted according to the plasticity theory and derivated the mathematic model showing definite physical meaning.
