摘要

摘要: 采用多介质弹塑性流体动力学计算方法，研制了适用于复杂加载的Lagrange计算程序MLEP，对劳伦斯利弗莫尔国家实验室（Lawrence Livermore National Laboratory，LLNL）19层和冲击波物理与爆轰物理国防科技重点实验室（Laboratory of Shock Wave and Detonation Physics，LSD）设计的29层Mg-Cu体系Pillow密度梯度飞片气炮加载实验过程进行了数值模拟和比较，获得的速度剖面计算结果与实验测试结果吻合一致，验证了流体动力学计算方法、不同材料体系混合模型以及计算程序的有效性和实用性，为进一步开展可控路径的复杂加载实验研究奠定了基础。

Abstract: The present study is for verification and validation (VV)of the onedimensional elastic-plastic hydrodynamic code MLEP (Multi-material Lagrangian Elastic-Plastic) and method of the mixing model of different material system. Two gas gun experiments with pillow impactor loading were calculated by MLEP, in which one is from the Lawrence Livermore National Laboratory (LLNL) of 19 layers model and the other is from the National Key Laboratory for Shock Wave and Detonation Physics Research (LSD), Institute of Fluid Physics CAEP of 29 layers model. Our simulation results are excellently consistent with the experiments. The work that we have carried out in this paper will become a part of VV and of the further research of controllable loading experiment.
