Abstract

The task of upgrading the accuracy of physical models of elastic wave emission, which is necessary for improving methods of acoustic-emission (AE) testing of materials and structures, is closely related to the problem of instability and ambiguity of measured parameters. We suggest solving the problem by modifying the models and creating new physically justified algorithms for digital processing of AE data. The paper considers underlying mathematical and physical principles of the algorithms and their applications to specific cases of bodies tested under constants loads and loads growing with constant rates. The algorithms have been tested on samples with adhesive bonds and on pressurized vessels.
