The Use of Shock Loading when Testing Fragile Objects by the Acoustic Emission Method

Bekher, S. A., Popkov, A. A.

Article language: Russian

Abstract. The article discusses the results of experimental studies using shock loading of glass objects by the method of acoustic emission. The scheme of the experiment is proposed, which allows to carry out a single shock action and damping of elastic vibrations of the controlled object. It was found that the relaxation of elastic stresses in the crack region after impact is satisfactorily described by the logarithmic dependence. A method is proposed for dividing the total signal flow into stationary groups by time intervals between signals and identifying mechanisms for the formation of elastic vibrations.

Keywords: emission, shock loading, signal clustering, crack, glass
