Growth of thermoplastic shear band
Journal of Materials Research and TechnologyShear localization is a fundamental and widely observed non-equilibrium phenomenon in metallic materials subjected to impulsive loadings. Despite extensive research over several decades, the evolution of shear bands still remains poorly understood.

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.

, 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

Competition between shear banding and wall slip in wormlike micelles [PDF]
, 2009 The interplay between shear band (SB) formation and boundary conditions (BC) is investigated in wormlike micellar systems (CPyCl--NaSal) using ultrasonic velocimetry coupled to standard rheology in Couette geometry.

Crossing of shears bands in 196Pb
Zeitschrift für Physik A Hadrons and Nuclei, 1996 High-spin states in 196Pb have been populated using the reaction 170Er(30Si,4n). The previously observed shears bands in this nucleus have been extended and some of their transitions have been reordered. They now form regular bands with band crossings. One of the bands splits into two pathways at high spin.

Dynamic interaction of multiple shear bands [PDF]
Scientific Reports, 2018 AbstractA mechanical model for waves impinging different configurations of multiple shear bands already formed in a ductile material, allows to analyze the ways in which dynamic interactions promote failure. It is shown that the presence of more than one shear band may lead to resonance and correspondent growth of a shear band or, conversely, to its ...

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.

Effect of cohesion on shear banding in quasi-static granular material [PDF]
, 2014 It is widely recognized in particle technology that adhesive powders show a wide range of different bulk behavior due to the peculiarity of the particle interaction. We use Discrete Element simulations to investigate the effect of contact cohesion on the

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 ...

Hidden spatiotemporal sequence in transition to shear band in amorphous solids
Physical Review Research, 2022 Localization of plastic flow into a narrow shear band is a fundamental and ubiquitous nonequilibrium phenomenon in amorphous solids. Because of the intrinsic entangling of three types of elementary local atomic motion—shear, dilatation, and rotation—the ...
