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 ...

Journal of Materials Research and Technology, 2022 High-entropy alloys (HEAs) containing nanotwins exhibit simultaneous high strength and great plasticity. The instantaneous formation mechanism of nanotwins in a shear band in the hot-extruded FeCoNiCrMo0.2 HEA has been investigated.

Shear-banding and microstructure of colloids in shear flow [PDF]
Faraday Discussions, 2002 We shall discuss the following phenomena found in various colloidal systems in shear flow. We recently observed shear-banding in suspensions of fd-virus in a cylindrical shear cell. Small angle light scattering experiments revealed that the shear-banding transition is preceded by a relatively fast process (minutes) of nematic-to-paranematic phase ...

A mechanism of failure in shear bands [PDF]
Extreme Mechanics Letters, 2018 We have carried out dilatant plasticity simulations to investigate the process of failure inside a shear band. The constitutive model accounts for possibly inhomogeneous flow within the band, void rotation and void elongation. We found that the material in the band may soften with no increase in the void volume fraction.

Viscous shear banding in foam [PDF]
Physical Review E, 2008 Shear banding is an important feature of flow in complex fluids. Essentially, shear bands refer to the coexistence of flowing and nonflowing regions in driven material. Understanding the possible sources of shear banding has important implications for a wide range of flow applications.

Study on Physical and Mechanical Characteristics of Shear Band in Jinpingzi Landslide Region II
Frontiers in Physics, 2022 The shear band is an important portion of a landslide. Investigating the shear band’s physical characteristics is one of the most significant challenges for landslide stability analysis and control. A systematic study of shear band in Jinpingzi landslide

Calorimetric consequences of thermal softening in Johnson–Cook’s model [PDF]
, 2013 At high loading rates, the development of adiabatic shear bands in metals is conventionally attributed to the strong interactions induced by viscoplastic dissipation within the bands and thermal softening effects.

Micromechanics of shear banding [PDF]
Mechanics of Materials, 1994 Abstract Shear-banding is one of many instabilities observed during the plastic flow of solids. It is a consequence of the dislocation mechanism which makes plastic flow fundamentally inhomogeneous, and is exacerbated by local adiabatic heating.

Shear Band Formation in Amorphous Materials under Oscillatory Shear Deformation
Metals, 2020 The effect of periodic shear on strain localization in disordered solids is investigated using molecular dynamics simulations. We consider a binary mixture of one million atoms annealed to a low temperature with different cooling rates and then subjected
