In this paper the numerical analysis of the drawing process with the blankholder is presented. The influence of the value of the blankholder force on the value of the drawing force and drawpiece height is examined. A different friction coefficient of the sheet metal for die and blankholder is considered. A defect at the lack of the blankholder is presented. The analysis in the system ANSYS/LS‐DYNA is passed. The material model with the mixed hardening, isotropic and isothermal is used. Technological parameters of the sheet‐metal to drawing, the die, the stamp and the blankholder from the literatures are chosen. Examples results of computer simulations are presented.
