Results of studying regularities in the development of cracks in glass under impact loading using the method of acoustic emission (AE) and tensometry are presented. An experimental setup has been developed that provides a single dynamic action with further damping of elastic vibrations in a test object. It has been established that the relaxation of elastic stresses occurring near the crack after the impact is described by a logarithmic dependence. The parameters of the amplitude and time distributions of AE signals have been determined. A technique is proposed for dividing the total flow of AE signals into stationary groups with an exponential distribution of time intervals between the signals.
