It is established that, in cases of localized fracture, the AE energy distribution has a commonly accepted shape described by a power law, while a dispersed fracture is characterized by an exponential energy distribution of the AE signals. Analysis of the functional form of the energy distribution performed at the early stage of loading allows one to recognize a spatial region in the sample where localization of the defect formation will subsequently take place. date: 2013-07 date_type: published publication: Technical Physics Letters volume: 39 number: 1 publisher: MAIK Nauka/Interperiodica pagerange: 112-115 id_number: doi:10.1134/S1063785013010331 refereed: TRUE issn: 1063-7850 official_url: http://dx.doi.org/10.1134/S1063785013010331 access_IS-EPOS: limited owner: Publisher citation: Damaskinskaya, E.
