| Abstract: | In the mechanical expanding of line|pipe,like other die|forming technology,the shape and size of expanding punch have great influences on the expending process.The purpose of study on this process lies in finding out the interrelation of them.In this paper numerical simulation on the mechanical expanding process of line pipe is made by means of elastic|plastic FEM analysis software|MARC.The influence of sectorial angle on deformation characters is especially analyzed,and some useful results are gained. |
| Keywords: | line pipe mechanical expanding numerical simulation |
