Quartz c-axis fabric characterization of the strike-slip ductile deformation within the Three Pagodas shear zone, western Thailand [PDF]
Heliyon, 2022 The Three Pagodas shear zone is associated with mainland Southeast Asia deformations. The evolution of the shear zone is divided into deformation phases D1a, D1b, and D2.

Evolution of shear zones in granular materials [PDF]
Physical Review E, 2014 The evolution of wide shear zones (or shear bands) was investigated experimentally and numerically for quasistatic dry granular flows in split bottom shear cells. We compare the behavior of materials consisting of beads, irregular grains (e.g.

The shear mechanical properties of rocks with variable angle joints [PDF]
Scientific ReportsVariable angle structural surfaces are more common in slopes. However, variable-angle joints have still been approximated as single-angle straight joint planes for analysis in previous studies, which failed to comprehensively capture the mechanical ...

Effect of Local Cyclic Loading on Direct Shear Strength Characteristics of Shear-Zone Soil
Applied Sciences, 2022 The reservoir landslide in the Three Gorges Reservoir Area (TGRA) often suffers from local cyclic loading scenarios produced by surge waves, groundwater level fluctuation, traffic loading, and seismic activity.

Friction of Shear-Fracture Zones [PDF]
Physical Review Letters, 2017 A shear fracture of brittle solids under compression undergoes a substantial evolution from the initial microcracking to a fully formed powder-filled shear zone. Experiments covering the entire process are relatively easy to conduct, but they are very difficult to investigate in detail. Numerically, the large strain limit has remained a challenge.

In Situ Shear Test for Revealing the Mechanical Properties of the Gravelly Slip Zone Soil
Sensors, 2020 Slip zone soil is usually composed of clay or silty clay; in some special geological environments, it contains gravels, which make the properties of the slip zone soil more complex.

Water pumping in mantle shear zones [PDF]
Nature Communications, 2017 AbstractWater plays an important role in geological processes. Providing constraints on what may influence the distribution of aqueous fluids is thus crucial to understanding how water impacts Earth’s geodynamics. Here we demonstrate that ductile flow exerts a dynamic control on water-rich fluid circulation in mantle shear zones.
