Monitoring shear deformation of sliding zone via fiber Bragg grating and particle image velocimetry
Journal of Rock Mechanics and Geotechnical EngineeringMonitoring shear deformation of sliding zones is of great significance for understanding the landslide evolution mechanism, in which fiber optic strain sensing has shown great potential.

Finite width of quasistatic shear bands [PDF]
Physical Review E, 2008 I study the average deformation rate of an amorphous material submitted to an external uniform shear strain rate, in the geometry known as the split-bottom configuration. The material is described using a stochastic model of plasticity at a mesoscopic scale.

Karl Popper and the Mechanisms of Hydrogen Embrittlement
Advanced Engineering Materials, EarlyView.Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

An Approximate Method for Evaluating the Shear Band Thickness in Saturated Soils
, 2004 formula for the thickness of a shear band formed in saturated soils under a simple shear or a combined stress state has been proposed. It is shown that the shear band thickness is dependent on the pore pressure properties of the material and the ...

Indentation-Induced Shear Band Formation in Thin-Film Multilayers
Frontiers in Materials, 2017 We report an exploratory investigation into the cause of shear band formation in multilayer thin films subject to nanoindentation. The material system considered here is composed of alternating aluminum (Al) and silicon carbide (SiC) nanolayers, atop a ...

Advanced Engineering Materials, EarlyView.Copper‐based composites enhanced with carbon feature convenient mechanical properties and favorable electric conductivity. Processing via deformation and thermomechanical treatments can introduce advantageous microstructures further enhancing their performance. Herein, copper–graphene powder‐based composites are directly consolidated via rotary swaging

Shear-Induced Changes of Electronic Properties in Gallium Nitride
, 2018 We show that sliding on the surface of GaN can permanently change the surface band structure, resulting in an increased degree of band bending by more than 0.5 eV.

Simulations of Fine-Meshed Biaxial Tests with Barodesy
Geosciences, 2018 Recent experimental studies showed that shear band development starts at the beginning of triaxial tests. In experimental testing, it is impossible to obtain a soil sample with a homogeneous void ratio.
