| Abstract: | This paper simulates the spinning deformation of thin walled tube in necking process with a dynamic explicit FEM program,LSDYN-A3D.The longitudinal strain,meridional strain and thickness distribution are analyzed at certain time and through time history.This paper first establishes a whole understanding of the deformation in necking process by spinning. |
