Visualization technology and application analysis of shearing tests for different kinds of soil

Shenzhen Daxue xuebao. Ligong ban, 2023
In order to study the application of visualization technology in shear tests of soil and the deformation mechanism of shear band, shearing tests on different kinds of soil are carried out by using the visualization shear equipment. Combining with digital

Formation of bulk-laminated materials by localized deformation during ECAP of an AA6060 aluminum alloy [PDF]

MATEC Web of Conferences, 2020
This paper addresses localized plastic flow during equal-channel angular pressing (ECAP) of an AA6060 aluminum alloy. We observe an alternating formation of shear bands and matrix bands during ECAP that leads to pronounced strain partitioning without ...

Prediction of Shear Localisation in Granular Materials based on a Critical State Non-coaxial Model [PDF]

E3S Web of Conferences, 2019
Experimental evidence indicates that the shear localisation acts as a precursor to the failure in biaxial compression tests of granular materials. Once formed they are persistent and lead to progressive failure of most geotechnical structures.

Adiabatic shear bands produced in a metallic armor, after dynamic compression with a Hopkinson pressure bar

Journal of Materials Research and Technology, 2022
A Brazilian high hardness armor (HHA) steel was, for the first time dynamically tested and microstructurally analyzed for the occurrence of shear bands.

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.

Effects of pore diameter and B2–NiTi crystal on plasticity of amorphous Ni–Ti alloy based on molecular dynamics simulation

Journal of Materials Research and Technology, 2023
The poor plasticity of metallic glasses (MGs) limits its applicability as engineering materials. Therefore, it is particularly important to find ways to improve the plasticity of metallic glasses.

Numerical investigation of the influence of shear band localization on the resonant behavior in the VHCF regime

Theoretical and Applied Mechanics Letters, 2014
The monitored resonant behavior of fatigue specimens of metastable austenitic stainless steel (AISI304) is correlated with its damage accumulation in the very high cycle fatigue (VHCF) regime.

The Role of Deformation Bands in Dictating Poromechanical Properties of Unconsolidated Sand and Sandstone

Geochemistry, Geophysics, Geosystems, 2020
Cataclastic shear bands in sands and sandstones are typically stronger, stiffer, and exhibit lower permeability than the surrounding matrix, and therefore act as barriers to fluid flow.

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.
