Abstract:

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(LawrenceLivermoreNationalLaboratory,LLNL)19层和冲击波物理与爆轰物理国防科技重点实验室(LaboratoryofShockWaveandDetonationPhysics,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。
