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