Abstract

When interpreting acoustic emission (AE) observation data, a model of a crack in the form of a cavity in the shape of an oblate ellipsoid of revolution was used. When the length of its semi-minor axis tends to zero, the ellipsoid models a circular disc-shaped crack. Using data from two amplitude-frequency spectra of AE recorded during the destruction of a concrete sample, distributions of the power of acoustic radiation along the lengths of the semi-axes of the ellipsoidal cavities were constructed. It is shown that by the time the second spectrum is recorded, a redistribution of acoustic radiation occurs in favor of a discrete set of growing main cracks with high semi-major axis lengths and a small opening value.
