Calculation of stresses in the steel elements subjected to the influence of thermo-mechanical loads requires taking into account the influence of temperature on material mechanical properties, including stress-strain curve. In this paper, on the basis of Ludwik, Hollomon, Swift and Voce equations, the modelling of strain-hardening curves of S355J2H steel considering the influence of temperature is discussed. The consideration were made on the basis of experimental results published in the literature as stress-strain curves S355J2H steel for selected temperatures. The values of the parameters in the equations of the individual models were determined, which allowed to analytical description of the material strain-hardening curves.
