| Zusammenfassung |
| In this paper, we performed experiments of uniaxial compression of granite
samples and recorded time series of electromagnetic pulses during the
evolution of the catastrophic fracturing process. The cumulative energy
release of the electromagnetic emission (EME) up to the critical point at
the moment of rupture was then calculated. It was shown, that the validity
of the proposed hierarchy models for the catastrophic fracturing process of
composite materials, in analogy to critical phenomena, can be experimentally
established not only via acoustic emission data, but via electromagnetic
emission data as well. The above conclusion could be a useful tool for the
improvement of the earthquake prediction method, based on precursory
electromagnetic signals. |
