Furthermore, two opposite phenomena are addressed: the former concerning the apparent weakness of the San Andreas fault, the latter regarding the strong frictional behavior which appears at the nano-scale. An interpretation of these size effects on the friction coefficient is attempted making use of the renormalization group procedure which allows to explain the frictional phenomena over all the scales. date: 2005 date_type: published publication: International Journal of Solids and Structures volume: 42 number: 9–10 publisher: Elsevier pagerange: 2901 - 2910 id_number: 10.1016/j.ijsolstr.2004.10.001 refereed: TRUE issn: 0020-7683 official_url: http://www.sciencedirect.com/science/article/pii/S0020768304005670 citation: Carpinteri, Alberto and Paggi, Marco Size-scale effects on the friction coefficient.
