Carpinteri, Alberto and Paggi, Marco A fractal interpretation of size-scale effects on strength, friction and fracture energy of faults. Chaos, Solitons and Fractals, 39 (2). 540 - 546. ISSN 0960-0779 (2009)Full text not available from this repository.
Experimental results indicate that large faults involved in earthquakes possess low strength, low friction coefficient and high fracture energy, in comparison with data obtained according to small scale laboratory tests on the same material. The reasons for such an unexpected anomalous behaviour have been the subject of several researches in the past and are still under debate in the Scientific Community. In this note, we propose a unifying interpretation of these size-scale effects according to fractal geometry, which represents the proper mathematical framework for the analysis of the multi-scale properties of rough surfaces in contact. This contribution sheds a new light on the non-linear properties of friction and on the understanding the fundamental physics governing the scaling of the mechanical properties in geophysics from the laboratory to a planetary scale.
