Assessment of the critical values of stress and strain of material on the basis of analysis of uniaxial tensile test data
Journal Title: Autobusy. Technika, Eksploatacja, Systemy Transportowe - Year 2016, Vol 194, Issue 4
Abstract
In the article, a method of determining the critical level of deformation of ferritic steel S355JR on the basis of measurements of grain elongation is proposed. Tests were carried out on steel in two microstructure states: ferrite-pearlite and bainite. Parameter values for the Ramberg-Osgood law and true stress-strain dependencies were set. The results obtained were compared with the results obtained according to other methods.
