Sažetak
The presented mathematical model determines the stresses depending on the measured temperature changes and the associated deformations of the samples. Investigations were conducted by tensile testing machine Zwick 50 kN on the samples from low-carbon niobium microalloyed steel. The values of measured parameters were determined by using the methods of thermography and digital image correlation. The model is formulated on the basis of a multiple regression analysis of the relations between measured and calculated parameters. Verification and validation of the model showed a good agreement between the model and the system modeled.
