Using the numerical computing technique submitted thickness changing can be predicted for different cases of simulation. In case of high coefficients of friction and blank holder pressures the sheet thickness decreases more than with low values. For an ideally plastic material it is below that obtained when hardening is taken into account. Sheet thickness changing is greater with isotropy than with anisotropy. But vertical and planar anisotropy have the maximal influence.
