| Abstract: | With the great-deformation elastoplastic FEM theory and the FEM software DYNA3D(research edition),the numerical simulation on the process of locally and radially plastic shaping of the seamless steel pipe,when the punch groove dimension and the punch radius are changing,has been researched.Conclusions with important reference value to the control of the surface quality of seamless steel pipes are gained,which solved the surface impression problem in forming steel pipes. |
