Abstract The article discusses the possibility of using the local low-temperature thermal loading method in acoustic emission control (AE control). The method is based on the initiation of a local stress-strain state on metal construction, which is formed when a specific construction area is cooled from low-temperature carbon dioxide. The characteristics of signals from acts of acoustic emissions emanating from the crack tip on the metal plate are obtained and studied. The theoretical values of a stress intensity factor for the crack under the local low-temperature thermal loading are calculated. It is shown that under local low-temperature thermal loading, a power-law relationship of the acoustic emission total count with the stress intensity factor is observed. © 2022 The Authors.
