Mechanism of shear stress fluctuation and dropping of the soil-rock mixture
Shuiwen dizhi gongcheng dizhi, 2021 The shear stress-dropping (jump) of the soil-rock mixture (S-RM) exists under direct shear conditions. In this paper the main factors affecting the stress-dropping are explored with the large scale direct shear test.

Interface Instability in Shear-Banding Flow [PDF]
Physical Review Letters, 2006 We report on the spatio-temporal dynamics of the interface in shear-banding flow of a wormlike micellar system (cetyltrimethylammonium bromide and sodium nitrate in water) during a start-up experiment. Using the scattering properties of the induced structures, we demonstrate the existence of an instability of the interface between bands along the ...

Journal of Materials Research and Technology, 2023 Voids are probably the most widely studied type of manufacturing defects since they are often formed during material processing. In this paper, the fracture and plastic deformation of Cu/Cu64Zr36 crystalline/amorphous composites with different void ...

SHEAR BAND OBSERVATIONS AND DERIVATIONS OF REQUIREMENTS FOR A SHEAR BAND MODEL
Le Journal de Physique Colloques, 1985 Observations of shear banding in fragmenting cylinders and in dynamic punch tests were analyzed for guidance in development of a theoretical model. The fragmenting cylinder tests led to a micro-mechanical model containing nucleation and growth processes for micro shear bands.

Crossing of shears bands in 196Pb
Zeitschrift für Physik A Hadrons and Nuclei, 1996 High-spin states in 196Pb have been populated using the reaction 170Er(30Si,4n). The previously observed shears bands in this nucleus have been extended and some of their transitions have been reordered. They now form regular bands with band crossings. One of the bands splits into two pathways at high spin.

The genesis of adiabatic shear bands
Scientific Reports, 2016 AbstractAdiabatic shear banding (ASB) is a unique dynamic failure mechanism that results in an unpredicted catastrophic failure due to a concentrated shear deformation mode. It is universally considered as a material or structural instability and as such, ASB is hardly controllable or predictable to some extent.

Shear localization in quasi-two-dimensional frictionless hydrogel layer controlled by packing fraction and system geometry [PDF]
EPJ Web of ConferencesHow do packing fraction and system geometry a↵ect shear banding, which controls the entire system’s rheological properties? In this study, we demonstrate that both increases in packing fraction and in shear channel width decrease shear band width ...
