Core Precession and Global Modes in Granular Bulk Flow [PDF]
, 2005 A transition from local to global shear zones is reported for granular flows in a modified Couette cell. The experimental geometry is a slowly rotating drum which has a stationary disc of radius R_s fixed at its bottom.

Effect of Spatial Variations in Floodplain Vegetation on Bed Shear Stress Distribution [PDF]
长江科学院院报[Objective] This study aims to investigate the effects of different vegetation arrangements (parallel and staggered) in the junction zone between channel and floodplain in urban rivers on the spatial distribution of bed shear stress, and to reveal how ...

STRESS FIELD IN A SHEAR ZONE, AND FORMATION OF THE MAIN FAULT
Геодинамика и тектонофизика, 2021 Using the analytical approximation method, we calculated stress field parameters for cases with different relative positions of Riedel shears and loads required for shearing.

Rate dependent shear bands in a shear transformation zone model of amorphous solids [PDF]
, 2008 We use Shear Transformation Zone (STZ) theory to develop a deformation map for amorphous solids as a function of the imposed shear rate and initial material preparation.
