The paper is devoted to yield point determination based on the thermomechanical coupling that takes place in the material during its uniaxial tension. Experiments were performed on aluminum alloy and on austenitic steels. The stress value corresponding to the temperature minimum is treated as the critical resolved stress at which plastic deformation on the macroscopic scale begins. The obtained results are compared with values of stress which produces the irreversible strain equal to 0.2%. Such value of the stress is usually regarded as the yield point determined from the stress-strain curve. It is found that the values of yield point determined on the ground of the thermomechanical coupling are lower than these obtained from stress-strain curve.
