Shear Band Formation in Amorphous Materials under Oscillatory Shear Deformation
Metals, 2020 The effect of periodic shear on strain localization in disordered solids is investigated using molecular dynamics simulations. We consider a binary mixture of one million atoms annealed to a low temperature with different cooling rates and then subjected

Mechanism of shear stress fluctuation and dropping of the soil-rock mixture
Shuiwen dizhi gongcheng dizhi, 2021 The shear stress-dropping (jump) of the soil-rock mixture (S-RM) exists under direct shear conditions. In this paper the main factors affecting the stress-dropping are explored with the large scale direct shear test.

Shear-band arrest and stress overshoots during inhomogeneous flow in a metallic glass [PDF]
, 2012 At the transition from a static to a dynamic deformation regime of a shear band in bulk metallic glasses, stress transients in terms of overshoots are observed.

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

Nucleation properties of isolated shear bands [PDF]
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2020 Shear banding, or localization of intense strains along narrow bands, is a plastic instability in solids with important implications for material failure in a wide range of materials and across length scales. In this article, we report on a series of experiments on the nucleation of single isolated shear bands in three model alloys ...

Shear-banding and microstructure of colloids in shear flow [PDF]
Faraday Discussions, 2002 We shall discuss the following phenomena found in various colloidal systems in shear flow. We recently observed shear-banding in suspensions of fd-virus in a cylindrical shear cell. Small angle light scattering experiments revealed that the shear-banding transition is preceded by a relatively fast process (minutes) of nematic-to-paranematic phase ...

Shear bands in granular flow through a mixing length model [PDF]
, 2007 We discuss the advantages and results of using a mixing-length, compressible model to account for shear banding behaviour in granular flow. We formulate a general approach based on two function of the solid fraction to be determined.

Crossover from quasi-static to dense flow regime in compressed frictional granular media [PDF]
, 2013 We investigate the evolution of multi-scale mechanical properties towards the macroscopic mechanical instability in frictional granular media under multiaxial compressive loading.

Strain localization and shear band propagation in ductile materials
Frontiers 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 ...
