Sažetak
This paper proposes a new mathematical model for calculation of stresses on the basis of experimentally measured values of strains and temperature changes for niobium microalloyed steel. Construction of model was done using a multiple regression analysis of the measured values of temperature change, deformation and stresses at four different stretching rates. All investigations were conducted on samples from the niobium microalloyed steel, using thermography and digital image correlation during static tensile testing. Constructed model was tested and validated on the experimentally obtained results. Model showed a good agreement of calculated stress values with experimentally obtained ones.
