摘要

At the present time a number of experimental methods are widely used for both qualitative and quantitative estimation of the sheet metal behaviour under processing by forming. There exist some special features of sheet metal deformation and, therefore, it is not possible yet to apply one and only testing procedure for all types of forming operations. The paper gives a brief description of the bulge testing of planar isotropic sheet metals and also presents some preliminary results about the applicability of this method for work hardening curves evaluation using data for specimen areas out of pole and for strength estimation under hydrostatic or hydrodynamic loading.
