摘要：

Some features of the fracturing of silicate glass materials are considered. The brittle fracturing of glasses is shown to begin under small applied forces that are characterized by low-amplitude acoustic emission (AE) signals. The further propagation of a fracture is shown to be accompanied by a change in the amplitude-frequency characteristics of AE signals, which we propose to describe with a continuous wavelet transform. A criterion for estimating the brittle fracture of glass with the use of attendant AE signals is proposed.
