 abstract={The strain hardening parameters of steel, aluminium and brass sheets were determined by uniaxial and balanced biaxial (hydraulic bulging) tensile tests. Sheet thickness gradation in different points of hemisphere formed in bulge test was analysed. The Ho 11 om o n equation was used to described uniaxial and biaxial strain hardening curves, and a comparison of strain hardening exponent was performed. Both the mean value of strain hardening exponent n (which describe the strain hardening of the whole strain range) and differential n,-value were determined on the base of the results of uniaxial and biaxial testing. The influence of the stress-state on the strain hardening behaviour of the material, as well as strain localization process, under both deformation modes are analysed.},
