Fragmentation, the process of breaking apart into fragments, is caused by the propagation of
multiple fractures at different length scales. Such fractures can be induced by dynamic crack …

Fractal-geometry techniques are widely applied to the quantification of complex rock
structures. Important properties of such structures are (i) different scaling behaviour on …

New observations of the internal structure of the San Gabriel fault (SGF) are combined with
previous characterizations of the Punchbowl fault (PF) to evaluate possible explanations for …

This paper presents a study of the micromechanical behaviour of crushable soils. For a
single grain loaded diametrically between flat platens, data are presented for the tensile …

There are currently three major competing views on the essential geometrical, mechanical,
and mathematical nature of faults. The standard view is that faults are (possibly segmented …

Discrete-element modelling has been used to investigate the micro mechanics of one-
dimensional compression. One-dimensional compression is modelled in three dimensions …

This paper presents an analysis of the yielding and plastic hardening of uniformly-graded
samples of a silica sand subjected to one-dimensional normal compression. Single grains of …

Grain size data from the deposit of the 1987 Val Pola rock avalanche (central Italian Alps)
are compared with data concerning rock avalanching, rock fragmentation, and comminution …

We develop a 2D slip-weakening description of a self-healing slip pulse that propagates
dynamically in a steady-state configuration. The model is used to estimate patterns of off …

Grain size reduction and gouge formation are found to be ubiquitous in brittle faults at all
scales,,,, and most slip along mature faults is observed to have been localized within gouge …
