Fig. 3. Time dependence of the temperature data from the sensors during the cooling of the specimen by a low-temperature carbon dioxide.

4. Results and discussion As a result of reading the data of acoustic emission signals, the time dependence of the acoustic emissions total count was obtained. Also, in the computational software, the temperature fields are plotted along the "y" axis at each moment of loading. As a result of comparing the above data on the loading time, the relationship of the acoustic emissions total count with the stress intensity factor was determined, which is shown in Figure 4 on a log-log scale.
