- Abstract
Ensuring trouble-free operation of structures and constructions is an extremely important and urgent task. That is why scientists pay a lot of attention to development of new methods, equipment and procedural materials for their implementation in industry. Particular attention is given to the state of material of the structures and constructions for timely decision taking and avoiding accidents or emergencies. Investigation of changes of acoustic emission (AE) parameters at different stages of testing material samples is conducted. Development of approaches to analysis of the distribution of AE event parameters is presented in the work. Informative parameters the distributions of which need to be studied, were tentatively determined, proceeding from analysis of the data of numerous investigations of different materials. Developed algorithms and determined means for setting up analysis of distribution of AE event parameters were introduced into the working part and visual interface of EMA-3.92 program. It is established that changes of AE parameters have certain regularities which is demonstrated by the results of testing samples from 17GS steel, and they can be used for assessment of the state of materials, when performing AE control and monitoring.
