摘要：

A method for determining the time to the failure of specimens of welded joints on the basis of the automatic determination of the parameters of a micromechanical-destruction model and the time dependences of the number of registered acoustic-emission signals is presented. The possibilities of improving this technique on the basis of the statistical identification of the uniform-destruction stage, which determines the specimen strength, are considered.
