Fig. 4. The relationship of the acoustic emissions total count with the stress intensity factor for the local low- temperature thermal loading. 1 ¬– experimental data, 2 – theoretic formula (3)

Note that a power-law relationship of the acoustic emissions total count with the stress intensity factor was obtained, which fully corresponds to the experimental data obtained on testing machines by Builo (2017). The theoretical relationship of the acoustic emissions total count with the stress intensity factor is expressed by Danegan (1968) by the formula: = ∙ (3)
