| Zusammenfassung |
| Large hierarchically organized sets of elements (simulating
asperities in a fault) are loaded to the point of complete failure. The fracture
thresholds of individual elements are stochastically distributed, and the hierarchical
structure for load-transfer is of the fractal-tree type. During the breakdown process there
occur bursts (earthquakes) of several elements breaking simultaneously at a given load.
Using Monte Carlo simulations we compute the frequency of bursts versus their size. This
shows a gross power-law behaviour superimposed by a wavy pattern closely related to the
coordination number of the fractal tree used for the load-transfer structure. |
