Abstract
Acoustic emission occurs during the local dynamic restructuring of the material structure, which is irreversible. Such rearrangements include the nucleation of microcracks, plastic deformations, and phase transformations associated with changes in the crystal structure, and others. The sources of such changes can be geological processes that occur over a considerable period of time, and anthropogenic destruction that occurs almost instantly. An actual example of the latter is the damage to hydro technical structures in Ukraine, which occurred as a result of military operations. Research using the acoustic emission method can be aimed at establishing: 1) features of the acoustic emission parameters to choose the optimal measurement conditions during structural tests in industrial conditions; 2) connections of the acoustic emission parameters with the mechanical characteristics of the materials or with the parameters of the processes occurring during loading in the structure of the materials. Therefore, the application of the acoustic emission method makes it possible to determine the optimal parameters for conducting research on the technical conditions of materials constituting hydro technical structures. This makes it possible to evaluate the residual resource of the structures.
