Strain-gradient mediated local conduction in strained bismuth ferrite films. [PDF]
Nat Commun, 2019 It has been recently shown that the strain gradient is able to separate the light-excited electron-hole pairs in semiconductors, but how it affects the photoelectric properties of the photo-active materials remains an open question.

Extraordinary strain hardening by gradient structure [PDF]
Proceedings of the National Academy of Sciences, 2014 Significance Nature creates the gradient structure (GS) for a purpose: to make biological systems strong and tough to survive severe natural forces. For the grain-size GS, the deformation physics is still unclear. One wonders if the grain-size GS in the nanomicroscale would also benefit materials engineered by mankind.

Motion Driven by Strain Gradient Fields. [PDF]
Sci Rep, 2015 AbstractA new driving mechanism for direction-controlled motion of nano-scale objects is proposed, based on a model of stretching a graphene strip linked to a rigid base with linear springs of identical stiffness. We find that the potential energy difference induced by the strain gradient field in the graphene strip substrate can generate sufficient ...

Constitutive Model of Thin Metal Sheet in Bulging Test Considering Strain Gradient Hardening
Medžiagotyra, 2020 The study of the size effect was one of the most important subjects in the field of micro-forming. To investigate the stress of the thin sheet in the bulging test with the second order size effect, a constitutive equation considering the strain gradient ...

Strain gradient effects on concrete stress–strain curve [PDF]
Proceedings of the Institution of Civil Engineers - Structures and Buildings, 2012 The stress–strain characteristic of concrete developed in flexure is one of the essential parameters for the ultimate flexural strength design of reinforced concrete (RC) members. Currently, the stress–strain curve of concrete developed in flexure is obtained by scaling down the uniaxial stress–strain curve.

Switching a Polar Metal via Strain Gradients [PDF]
Physical Review Letters, 2021 Although rare, spontaneous breakdown of inversion symmetry sometimes occurs in a material which is metallic: these are commonly known as polar metals or ferroelectric metals. Their 'polarization', however, cannot be switched via an electric field, which limits the experimental control over band topology.

Strain-gradient effect on the crack tip dislocations density
Fracture and Structural Integrity, 2020 In this study, the influence of a material s plastic properties on the crack tip fields and dislocation density behavior is analytically and numerically analyzed using the conventional mechanism-based strain-gradient plasticity (CMSGP) theory established
