| Abstract: | This paper presents the research development of the meshless method such as SPH, RKPM and EFG and their applications in metal forming process. The differences between meshless method and finite element method are also introduced. Comparing with the finite element method , the advantages of meshless method in metal forming process are tested by the plain strain upsetting process. And the main problem and the developing trend are also introduced. |
| Keywords: | meshless method metal forming finite element upsetting |
