The rigid-plastic finite element method is used to establish the rigid-plastic finite element model of the high-stock during the compression between flat dies and to conduct numerical simulation. The method of applying transverse disturbance in the process of numerical simulation is discussed. The simulation results are finally obtained The influence of friction factor on the compression stability of blank
