Forming limit curves of deep drawing steel sheets have been determined experimentally and calculated on the base of the material tensile properties folIowing the Hill, Swift, Marciniak-Kuczyński and Sing-Rao methods. Only the FLC modelled from a singly linear forming limit stress curve exhibits good agreement with experimental curve. It was established that a linearized limit stress locus describes adequately the actual localised neck conditions for the material chosen in this study. The quantitative X-ray microanalysis of the Fe contents in the sheet surface layer composition was used to determine cracking limit curve (CLC) of electro-galvanized steel sheet. The change in zinc layer (and base sheet metal) thickness was used as a criteria in calculation of the CLC.
