Critical packing in granular shear bands [PDF]

Physical Review E, 2007
In a realistic three-dimensional setup, we simulate the slow deformation of idealized granular media composed of spheres undergoing an axisymmetric triaxial shear test.

Hardening of shear band in metallic glass [PDF]

Scientific Reports, 2017
Strain hardening, originating from defects such as the dislocation, avails conventional metals of high engineering reliability in applications. However, the hardenability of metallic glass is a long-standing concern due to the lack of similar defects. In

Coarse slip bands and non-Schmid’s translational slip lead to shear bands formation in body-centered cubic HfNbTaTiZr high-entropy alloy [PDF]

Scientific Reports
The microstructural evolution and shear band formation mechanism in an equiatomic HfNbTaTiZr body-centered cubic (BCC) high-entropy alloy (HEA) were systematically investigated during cold rolling. Microstructural observations revealed the development of

Shear bands and cracking of metallic glass plates in bending [PDF]

, 1997
The thickness dependence of yielding and fracture of metallic glass plates subjected to bending is considered in terms of the shear band processes responsible for these properties.

Evolution of Shear Band in Plane Strain Compression of Naturally Structured Clay with a High Sensitivity

Applied Sciences, 2022
The formation of the shear band is associated with the failure of soil. However, there has been relatively little investigation on the evolution of shear bands in naturally structured clay with a high sensitivity.

Understanding and suppressing shear band formation in strut-based lattice structures manufactured by laser powder bed fusion

Materials & Design, 2021
The formation of shear band in metallic lattice structures under compression prompts an unstable stress–strain curve, resulting in a significant reduction in the energy absorption capacity. The development and formation of shear band need to be clarified,

Soil Particle Movement and Shear Band Development during Plane Strain Compression [PDF]

E3S Web of Conferences, 2019
Most geotechnical structures failed by formation and development of shear bands in soils. Thus, shear deformation and shear bands development evaluation are necessary to understand shear failure mechanism.

Fluid Depletion in Shear Bands [PDF]

Physical Review Letters, 2012
How does pore liquid reconfigure within shear bands in wet granular media? Conventional wisdom predicts that liquid is drawn into dilating granular media. We, however, find a depletion of liquid in shear bands despite increased porosity due to dilatancy. This apparent paradox is resolved by a microscale model for liquid transport at low liquid contents

In Situ Generated Shear Bands in Metallic Glass Investigated by Atomic Force and Analytical Transmission Electron Microscopy

Metals, 2022
Plastic deformation of metallic glasses performed at temperatures well below the glass transition proceeds via the formation of shear bands. In this contribution, we investigated shear bands originating from in situ tensile tests of Al88Y7Fe5 melt-spun ...

Discrete element modeling of particles sphericity effect on sand direct shear performance

Scientific Reports, 2022
Particle surface morphology is an important factor influencing sand structure and mechanical properties. In this study, the effect of sand particle sphericity on sand direct shear performance is investigated by using the discrete element method (DEM ...
