| 摘 要： | 聚能射流形成的数值模拟,涉及到大变形、高应变率以及材料的破坏,传统的拉格朗日或欧拉方法在解决该问题均有很大的局限性,先后发展了网格重分、ALE、SPH等方法,以及界面处理技术,各有所长,但尚未完全解决,而在实际工作中,切合实际的药型罩介质本构关系则是聚能射流数值模拟的关键,高效并行计算与可视化则是聚能射流数值模拟的必由之路,并阐述了聚能射流数值模拟的发展趋势．

| Abstract: | The numerical simulation in shaped charge jet involves large deformation, high strain rate, and material damage. And traditional computational methods, Lagrangian and Eulerian, are limited in dealing with these problems. Therefore new numerical methods such as re-mesh, ALE, SPH, technology of interface disposal and so on are well developed. In practical shaped charge jet engineering analysis, the right different wall liner constitutive law is the key. The high effective parallel computing and scientific visualization are the only way for numerical simulation. And tendency with respect to numerical simulation of shaped charge jet is also comprehensively surveyed. |
