The genesis of adiabatic shear bands
Scientific Reports, 2016 AbstractAdiabatic shear banding (ASB) is a unique dynamic failure mechanism that results in an unpredicted catastrophic failure due to a concentrated shear deformation mode. It is universally considered as a material or structural instability and as such, ASB is hardly controllable or predictable to some extent.

Shear localization in quasi-two-dimensional frictionless hydrogel layer controlled by packing fraction and system geometry [PDF]
EPJ Web of ConferencesHow do packing fraction and system geometry a↵ect shear banding, which controls the entire system’s rheological properties? In this study, we demonstrate that both increases in packing fraction and in shear channel width decrease shear band width ...

The Size Effect of Shear Bands in Dense Sands—A Discrete Element Analysis
Applied SciencesThe localization of deformation in shear bands is a fundamental phenomenon in granular materials like soil. In this study, we focus on the characteristics of shear bands, particularly the size effect, by implementing biaxial discrete element method (DEM)

A Constitutive Model for Locally Drained Shear Bands in Globally Undrained Dense Sand [PDF]
E3S Web of Conferences, 2019 When saturated granular materials which are dilative in nature are subjected to the undrained deformation, their strength increases due to the generation of negative excess pore pressure.

Study on the Shear Band of Sand with Various Particle Characteristics Using PIV Analysis [PDF]
E3S Web of Conferences, 2019 The phenomenon of ground undergoing large plastic deformation, leading to collapse, occurs due to the localization of unstable deformation. The investigation of shear band is important in order to understand the destructive phenomenon.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase
FEBS Letters, EarlyView.Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

The dynamics of a shear band [PDF]
Journal 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

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies
FEBS Open Bio, EarlyView.We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...
