Some Possibilities of Determination of Yield Conditions for Cold Rolled Steel SheetsDOI: 10.2478/v10147-011-0031-y Keywords: Steel Sheets, Anisotropic Plasticity, Yield Conditions, Biaxial Tensile Test, Cruciform Specimen, Digital Image Correlation Abstract: Rolling of metallic materials results to anisotropy of their mechanical properties during plastic deformation. In the paper are described some possibilities of analytical and experimental determination of conditions for plastic deformation of cold rolled steel sheets. The experimental analysis is realized by biaxial tensile test with application of strain gage and optical methods. The results gained by experimental procedures are compared with yield conditions according to individual theories.
