The article is focused on the stress analysis of plane specimens made from hypocutectoid steel, using digital image correlation. It is steel used in the manufacture of railway wheels for freight transport. The aim of the article is to measure the displacement fields by using digital image correlation, from which the strain fields are subsequently calculated. By processing the obtained values using the virtual fields method, the isotropic elastic constants and the hardening behaviour weredoi:10.4149/km_2014_5_313 fatcat:jroh2dgdajdpngc6wq4fwd7q7q
