The article is focused on identification the stress fields related to strain fields by using digital image correlation (DIC) and to verify the results obtained using the finite element method (FEM). Particular attention is devoted to the analysis of deformation in area of stress concentration (near notch). The virtual field method is using to determine the stress fields connected with displacement fields, which was elaborated for analysis of an elasto plastic deformation by Grédiac and Pierron. These procedures are applied to determine the properties of cold rolled steel used for automobile industry. For analysis was used uncoated sheet of isotropic steel with higher strength properties.

Keywords: strain fields, stress fields, virtual fields method, finite element method
