The modulus of elasticity is used not only to determine the value of the elastic strain, but in consequence also to determine the value of the total strain in the range of plastic strain. Therefore, the selection of the appropriate modulus for specific operating conditions is of decisive importance here. The paper presents a comparative analysis of the Young's modulus with cyclic moduli determined for the rising and falling loop, for the straight line connecting the edges of the hysteresis loop and the average moduli. The tests were carried out for Ti-6Al-4V titanium alloy at room temperature and cryogenic temperature. The conducted tests have shown that the values of cyclic moduli change during cyclic loads. The values of the cyclic moduli for the rising loop are larger than the Young's modulus.
