Zusammenfassung |
Non-linear time-sequences of fracture-related events were studied in
drifting sea-ice and fracturing rock. A reversible drop of the b-value was
detected prior to the large-scale sea-ice cover fragmentation, when the time
sequence of impact interactions between ice-fields was fully decorrelated. A
similar loss of the temporal invariance of the fracture process was revealed
in the time sequence of microfracture events detected in a loaded rock
sample. These temporal gaps in the continuous critical state of the
considered self-organizing, open systems were attributed to the property of
hierarchicity inherent in the geophysical objects. A combination of scaling
and hierarchic features in the behavior of fracturing solids manifests
itself in the heterogeneity of the temporal pattern of fracture
process. |
