Micromechanics of shear banding [PDF]

open access: yesMechanics 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.

Recrystallization Behavior of Warm Rolling and Cold Rolling Cr-Ti-B Steel during Annealing

open access: yesMetals, 2022
To study the nucleation and recrystallization behavior of deformation bands, shear bands and grain boundaries during the recrystallization process, a heat treatment test was carried out on Cr-Ti-B low-carbon steel after warm rolling and cold rolling. The

Formation of Micro Shear Bands During Severe Plastic Deformation of BCC Alloys [PDF]

open access: yesJournal of Stress Analysis, 2018
In this work, tendencies of pure Niobium, Fe-20Cr stainless steel, and Ti-36Nb-2Ta-3Zr to formation of micro shear bands inside their microstructures during severe plastic deformation are compared with their mechanical properties.

Non-linear oscillatory rheological properties of a generic continuum foam model: comparison with experiments and shear-banding predictions [PDF]

open access: yes, 2012
The occurence of shear bands in a complex fluid is generally understood as resulting from a structural evolution of the material under shear, which leads (from a theoretical perspective) to a non-monotonic stationnary flow curve related to the ...

Multiple shear bands in granular materials

open access: yesEPJ Web of Conferences, 2017
The transition regime from quasi-static to dynamic shear regime is studied by discrete element method (DEM) and by means of a mesoscopic model. We show that at moderate shear rate multiple shear bands appear which eventually appear as a continuous shear ...

Investigation of shear band strengthening by using different strengthening criteria [PDF]

open access: yesE3S Web of Conferences
To prevent a critical failure mechanism, it is possible to simply strengthen the potential shear bands, which is a patented idea. The localization of potential shear bands that are most likely to form shear can be calculated. Before these shear bands can

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

open access: yesShenzhen 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

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

open access: yesE3S 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

open access: yesJournal 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.
