Magnetic Resonance Imaging study of sheared granular matter [PDF]
arXiv, 2022 We introduce a Magnetic Resonance Imaging technique to study the geometry of shear zones of soft, low-frictional and hard, frictional granular materials and their mixtures. Hydrogel spheres serve as the soft, low-frictional material component, while mustard seeds represent rigid, frictional grains. Some of the hydrogel spheres are doped with CuSO4 salt

The role of the Ranotsara Zone in southern Madagascar for Gondwana correlations [PDF]
, 2006 The Precambrian basement of southern Madagascar was reworked at high-grade metamorphic conditions during the East African Orogen (EAO of Stern, 1994) that formed during assembly of Gondwana in late Neoproterozoic/early Paleozoic times.

Magnetic buoyancy instabilities in the presence of magnetic flux pumping at the base of the solar convection zone [PDF]
, 2012 We perform idealized numerical simulations of magnetic buoyancy instabilities in three dimensions, solving the equations of compressible magnetohydrodynamics in a model of the solar tachocline.

Coexistence and Transition between Shear Zones in Slow Granular Flows [PDF]
Phys. Rev. Lett. 111, 148301 (2013), 2013 We report experiments on slow granular flows in a split-bottom Couette cell that show novel strain localization features. Nontrivial flow profiles have been observed which are shown to be the consequence of simultaneous formation of shear zones in the bulk and at the boundaries. The fluctuating band model based on a minimization principle can be fitted

Fluid pressurisation and earthquake propagation in the Hikurangi subduction zone [PDF]
, 2021 In subduction zones, seismic slip at shallow crustal depths can lead to the generation of tsunamis. Large slip displacements during tsunamogenic earthquakes are attributed to the low coseismic shear strength of the fluid-saturated and non-lithified clay-rich fault rocks.

Shear Strength Characteristics of Clay-Gravel Layer and Its Slope Failure Law and Mechanism
Frontiers in Earth Science, 2022 The Anqing Formation clay-gravel layer is widely distributed in the Anqing area of the upper reaches of the Wanjiang River. It is a typical soil-rock mixture composed of gravel and clay.

Multiphase gas transport in a shear zone
, 2023 In the post-operational phase of a Low/Intermediate-Low radioactive waste repository, gas will be generated in the caverns due to anaerobic corrosion of metals, and also chemical and microbial degradation of organic substances. Previous investigations on gas migration have indicated that discrete water conducting features (e.g. shear zones) are mainly

Shear zones in granular mixtures of hard and soft particles with high and low friction [PDF]
arXiv, 2023 Granular materials show inhomogeneous flows characterized by strain localization. When strain is localized in a sheared granular material, rigid regions of a nearly undeformed state are separated by shear bands, where the material yields and flows. The characteristics of the shear bands are determined by the geometry of the system, the micromechanical ...
