| 中文摘要: |
| 无网格法是一种新兴发展的数值计算方法,作为有限元法的一种重要补充在冲击动力学领域得到了广泛的应用。本文从求解过程上对无网格法和有限元法进行了比对分析,针对SPH、RKPM、EFG三种典型无网格法的基本原理及其在冲击动力学方面的应用进行了阐述,并提出无网格法的发展方向。 |

| ion: The meshless method is emerging developing numerical method, which seen as supplement for mesh computation is widely applied to impact dynamics. In this paper, meshless method is analyzed compared with finite element method from solving process. Then, the basic principles and the application in impact dynamics are introduced about three topical meshless methods SPH, RKPM, EFG. Finally the development tendency of meshless method is presented. |
