The work contains the results of experimental researches and numerical simulations of friction test that simulate the friction conditions in drawbead during sheet metal forming. The numerical model of the drawbead friction simulator test has been created using MSC.Marc + Mentat 2010. Simulations have been performed to determine a stress state in pulled sample during the drawbead simulator test. The isotropic and two anisotropic Hill (1948) and Barlat (1991) material models were used in simulations taking into consideration sample orientation according to the rolling direction of the sheet. The samples for friction tests were cut along and transverse to the rolling direction of the sheet. It was found that the yield criterion has a strong influence on the distribution and the value of normal and shear stresses in the sample. Furthermore, the values of analyzed stresses were changed in the sample width.
