Methods of Acoustic Emission Diagnostics of Pre-Destruction State

In this paper discusses ways of measuring equipment and, in particular, to a method for monitoring and diagnosis based on the use acoustic emission (AE). Offered by methods can be applied: 1.During cyclic fatigue test different constructions in order to assess their technical condition; 2.During test on the residual strength constructions, as well as in monitoring and diagnosis of technical condition of machines and heavy-duty construction for which the functioning is limited to the damage or unacceptable. 3.To estimate process of destruction of composite structures consisting of a matrix and unidirectional reinforcing elements (fibers
