Theoretical Foundations of the Method of Acoustic Emission for the Diagnostics of Delayed Fracture of Materials

We present a survey of the results of theoretical investigations of the method of acoustic emission used for the determination of the limit equilibrium of materials with cracks, their delayed fracture (initiation and propagation of cracks), and the residual service life of structural elements intend...

Description
Summary:We present a survey of the results of theoretical investigations of the method of acoustic emission used for the determination of the limit equilibrium of materials with cracks, their delayed fracture (initiation and propagation of cracks), and the residual service life of structural elements intended for long-term operation. At the same time, we develop computational models for the detection, by the acoustic-emission method, of crack-like defects and volumetric damage to the materials. We also propose criteria for the mechanisms of their fracture and acoustic-emission procedures aimed at the construction of the kinetic diagrams of delayed growth of creep cracks.
