The dynamics of a shear band [PDF]

open access: yesJournal of the Mechanics and Physics of Solids, 2018
A shear band of finite length, formed inside a ductile material at a certain stage of a con- tinued homogeneous strain, provides a dynamic perturbation to an incident wave field, which strongly influences the dynamics of the material and affects its path to failure. The investigation of this perturbation is presented for a ductile metal, with reference

Enhancement of punching shear strength of flat slabs using shear-band reinforcement

open access: yesHBRC Journal, 2018
Flat-slab system is widely used nowadays. Major and critical problem of this system is its sudden brittle failure is called punching shear failure. To overcome the punching failure problem, there are many ways to increase the punching shear strength of ...

Strain localization and shear band propagation in ductile materials

open access: yesFrontiers in Materials, 2015
A model of a shear band as a zero-thickness nonlinear interface is proposed and tested using finite element simulations. An imperfection approach is used in this model where a shear band, that is assumed to lie in a ductile matrix material (obeying von ...

Shear‐Band Dynamics in Metallic Glasses

open access: yesAdvanced Functional Materials, 2015
The future of metallic glasses as an advanced structural and functional material will to a great extent depend on the understanding and control of their mesoscopic flow defects called shear bands. These defects are sweet‐and‐sour; sweet because they mediate macroscopic plasticity at room temperature, and sour because they quickly promote failure.

Dilatancy induced ductile-brittle transition of shear band in metallic glasses. [PDF]

open access: yesProc Math Phys Eng Sci, 2018
Dilatancy-generated structural disordering, an inherent feature of metallic glasses (MGs), has been widely accepted as the physical mechanism for the primary origin and structural evolution of shear banding, as well as the resultant shear failure ...

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

open access: yesApplied 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

open access: yesMaterials & 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]

open access: yesE3S 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]

open access: yesPhysical 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

open access: yesMetals, 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 ...
