摘要
针对多物质弹塑性流体动力学问题提出了一种Euler型有限差分算法。基于该算法,用面向对象的C++语言编译了MMIC-2D计算程序,开发了与之相配套的前处理软件MESH-2D、后处理可视化软件VISC-2D,并对球形装药土中爆炸这类典型的爆炸问题进行了二维数值模拟。数值模拟结果与实验结果相吻合,表明文中所提出的算法和计算程序合理、有效,可以用于进行工程数值仿真计算。
In this paper, a 2-D Eulerian finite difference method for multi-material etasuc-ptastic hydrodynamic problems is presented. Based on this method, the calculation program MMIC- 2D using C++ is compiled and the preprocessing and visualization software VISC2D are developed. The cavity formation and development process of spherical charge exploding in soil medium are numerically simulated. The simulation results are found to be in a good agreement with the principle of physics and experimental data, which indicates that the algorithm and calculation code presented in this paper are reasonable and can be used to simulate engineering problems.
