“…After yielding, the cementation breaks and the soil eventually returns to the behaviour of the uncemented soil. Examples of behaviour during isotropic compression can be found in, for example, Coop and Atkinson (1993), Leroueil and Vaughan (1990) and Cuss et al (2003).…”

“…Shear bands are localised strains often 4-10 grain diameters wide, with further damage restricted to within approximately 2 mm of the shear band (Cuss et al, 2003;El Bied et al, 2002). Scanning electron microscope images obtained by El Bied et al (2002) show that tests performed under low confining pressure have a shear zone characterised by grain cracking with no grain crushing, while tests performed under high confining pressure have a shear zone characterised by grain crushing and pulverisation.…”

111The behaviour of cemented soil and the role of cementation are reviewed based on experimental results. The review is presented in terms of geomechanics concepts in which the cemented soil may be modelled by elasticity and hardening plasticity concepts. No modelling equations are given, but the observed behaviour is analysed in view of the components entering into an elastoplastic model. These consist of an elastic range in stress space in which energy is not created or expended, a cementation yield surface, a 3D failure surface, a plastic potential, a yield surface and the associated plastic hardening law.

“…On the other hand the use of Critical State Soil Mechanics (CSSM) has also been adopted (e.g. SHAH, 1997;CUSS et al, 2003;SHELDON et al, 2006) to analyse the mechanical and permeability evolution of faulted rocks. Our study focuses on the material within the cataclasite layer ( Fig.…”

We develop a constitutive model for rocks that are constituted from brittle particles, based on the theory of breakage mechanics. The model connects between the energetics and the micromechanics that drive the process of confined comminution. Given this ability, our model not only describes the entire stress-strain response of the material, but also connects this response to predicting the evolution of the grain size distribution. The latter fact enables us to quantify how the permeability reduces within cataclasite zones, in relation to aspects of grain crushing. Finally, our paper focuses on setting a framework for quantifying how the energy budget of earthquakes is expensed in relation to dissipation events in cataclasis. We specifically distinguish between the dissipation directly from the creation of new surface area, which causes further breakage dissipation from the redistribution of locked-in stored energy from surrounding particles, dissipations from friction and from the configurational reorganisation of particles.

“…These aspects of Ernie's work will be considered further in the context of lower crustal deformation. More recently Ernie has used soil mechanics in a more conventional fashion, to investigate the strength of porous sandstones (Cuss et al 2003;Rutter & Glover 2012). This research shows that the critical-state line is independent of rock type and can be related to Byerlee's frictional sliding relationship (Fig.…”
