On this paper the numerical analysis of the drawing process on the curved line drawing die is presented. The incremental model of the process in updated Lagrangian formulation with the regard of the geometrical and physical nonlinearity has been evaluated by variational and the finite element methods. The Frederic Barlat's model taking into consideration the anisotropy of materials in three main and six tangents directions has been used. The work out application in ANSYS/LS-DYNA program allows complex step by step analysis and prognoses: the shape, dimensions and state stress and strains of drawpiece. It is possible to calculate necessary value of the drawing force and it's changeability during the process and energy consumption. Sample results of computer simulations dependence drawing force from stamp displacement and comparison with experiment are presented. The sheet metal thickness in the characteristic drawpiece locations and drawpiece height has been calculated. A numerical calculation has been confronted with experimental results. The numerical analysis of the drawpiece spring back after takes it out of the drawing die is realized.
