Abstract

This paper presents comparison of the stress and strain fields gained by a digital image correlation (DIC) and FEM. This method was used to determine strain fields in narrow range of planar specimen. These strain fields were used for calculation of the stress fields by virtual fields method (VFM). The specimen was made from the hypoeutectoid ferrite-pearlite steel, which was used in production of train wheels. The analysis was carried out using two-dimensional DIC by which were obtained values of the strain fields. These values were measured on the surface of specimen in the elastic and plastic domain. Based on measured strain fields the stress fields were determined by Matlab software. Values obtained by this method were subsequently compared with those achieved by FEM.
