Post-seismic stress relaxation with a linear transient rheology
Transient rheology Geodynamics Stress tensor Coulomb failure function Post-seismic relaxation
2015/8/28
We performed an analysis of post-seismic stress relaxation, taking into account generalized linear rheologies. We compared the stress field (and its derived functions) obtained with a classical Maxwel...
Cooling of a channeled lava flow with non-Newtonian rheology: crust formation and surface radiance
Rheology Magmas Thermodynamics Lava flow Effusion rate
2015/8/27
We present here the results from dynamical and thermal models that describe a channeled lava flow as it cools by radiation. In particular, the effects of power-law rheology and of the presence of bend...
Landslide velocity, thickness, and rheology from remote sensing: La Clapière landslide, France
Landslide velocity thickness rheology from remote sensing La Clapière landslide France
2014/4/8
Quantifying the velocity, volume, and rheology of deep,slow-moving landslides is essential for hazard prediction and understanding landscape evolution, but existing field-based methods are difficult o...
Constraints from rocks in the Taiwan orogen on crustal stress levels and rheology

Taiwan’s Hsüehshan range experienced penetrative coaxial deformation within and near the brittle-plastic transition between6.5 and 3 Ma. This recent and short-lasting deformation in an active, well-s...
Influence of Non-Newtonian rheology on magma degassing
Non-Newtonian rheology magma degassing Soft Condensed Matter
2011/8/4
Abstract: Many volcanoes exhibit temporal changes in their degassing process, from rapid gas puffing to lava fountaining and long-lasting quiescent passive degassing periods. This range of behaviors h...

Model self-assembled networks of telechelic polymer C18 −PEO(35k)−C18 in water have been studied. The rheology of such transient networks has been investigated as a function of polymer con...
The large-scale two-dimensional rheology of a sea ice pack arises from the local contact forces between adjacent does in convergence. It is conventionally modeled by a viscous-plastic constitutive rel...
Asymptotic Stability of the Viscous–Plastic Sea Ice Rheology
Asymptotic Stability Viscous–Plastic Sea Ice Rheology
2008/12/3
The stability of the viscous–plastic rheology used extensively to model the dynamics of large–scale sea ice covers is studied. Using energy methods, it is shown that on a bounded domain, the viscous–p...
Change in ice rheology during climate variations – implications for ice flow modelling and dating of the EPICA Dome C core
ice rheology ice flow EPICA Dome C core
2008/11/4
The study of the distribution of crystallographic orientations (i.e., the fabric) along ice cores provides information on past and current ice flow in ice-sheets. Besides the usually observed formatio...
Loss of Hyperbolicity and Ill-posedness of the Viscous–Plastic Sea Ice Rheology in Uniaxial Divergent Flow
Loss of Hyperbolicity Ill-posedness Viscous–Plastic Sea Ice Rheology Uniaxial Divergent Flow
2008/7/23
Local contact interactions between sea ice floes can be modeled on the large scale by treating the pack as a two-dimensional continuum with granular properties. One such model, which has gained promin...
Effects of Rheology and Ice Thickness Distribution in a Dynamic–Thermodynamic Sea Ice Model
Effects of Rheology Ice Thickness Distribution Dynamic–Thermodynamic Sea Ice Model
2008/7/22
Realistic treatment of sea ice processes in general circulation models is needed to simulate properly global climate and climate change scenarios. As new sea ice treatments become available, it is nec...
