The stress-strain relationship of the deep drawing quality (DDQ) and intersitial free (IF) steel sheets was determined by uniaxial and equibiaxial (hydraulic bulging) tensile tests. The sheet thickness gradation in different points of the hemisphere formed in the bulge test was analysed, both experimentally and theoretically. The Hollomon equation was used to describe uniaxial and biaxial strain hardening curves, and the differential (strain dependent) strain hardening exponent nt was determined on the basis of the results of uniaxial and biaxial testing.
