The problem of calculations and experimental validation of residual stresses in hot-rolled strips is considered in the paper. Residual stresses become of practical importance when the laser cutting of strips is applied. The goal of this paper is development and experimental validation of a model of residual stresses in hot-rolled strips based on the elastic-plastic material model. The models of elastic-plastic deformation during cooling of hot rolled strips during laminar cooling and in the coil were developed. Elastic-plastic properties of the material were determined experimentally using tests on GLEEBLE 3800. Industrial testing of residual stress in strips after cooling in coil was performed. For measurement of residual stress in strips the X-ray diffraction method was used. (C) 2015 Politechnika Wroclawska. Published by Elsevier Sp. z o.o. All rights reserved.
