摘要: 介绍温度的数值模拟方法,采用三维动力学有限元程序模拟冲击压缩状态,分析了数值模拟的准确性。模拟了铜和铝两种金属单质组成混合物的冲击压缩性能,在分析了热传导影响后,计算了混合物的冲击温度和冲击绝热线。Abstract: Several numerical methods to estimate temperature of mixtures during shock loading are introduced. Numerical results of shock compression behaviors of mixtures simulated using a 3D hydrodynamic finite element code are in good agreement with these from Hugoniot equations. On analyzing the effect of heat conduction, the shock temperature of the mixture and the shock Hugoniot curve are obtained.
