摘要
On the basis of a model for describing the processes of acoustic emission (AE) and the relationships following from it and relating the AE parameters to the structural and physical characteristics of a solid subjected to damage, AE processes are mathematically simulated. It is shown that the morphology of the AE amplitude-frequency spectrum is determined by both the crack-size distribution function and the dependences of the displacement amplitude of interphase surfaces and the difference of elastic stresses on the surfaces of radiating cracks on their effective radius.
