The numerical simulation for four pass cogging of H beam has been conducted by finite element method with software ANSYS/LS-DYNA. The selection of material models,the determination of element types and the meshing in this simulation were introduced in details.The simulation results of workpiece's deformation after each pass were received.The deformation of workpiece and stress field in rolling area were analyzed.This paper provides references for the simulation of the special shaped steel rolling process by DEM.
