Giant optical enhancement of strain gradient in ferroelectric thin films and its physics origin [PDF]
arXiv, 2015 The coupling between strain gradients and polarization, known as flexoelectricity, offers a new mechanism to control the functionality of dielectric materials. However, for the effect to be practically attractive, dynamic control of the strain gradient with magnitudes far exceeding those achievable via mechanical deformation (~10 $m^{-1}$) is needed ...

Strain hardenability of a gradient metallic alloy under high-strain-rate compressive loading
Materials & Design, 2019 Subjected to an impact loading, metallic alloys usually display strain softening due to the highly localized shear deformation accompanied by temperature rise, which causes the decrease of resistance to an applied loading and even catastrophic failure ...

The ab-initio aided strain gradient elasticity theory
Fracture and Structural Integrity, 2019 When the width of cracked nanocomponents made of brittle or quasi-brittle materials is less than approximately , the size of the - dominance zone becomes smaller than and comparable to the fracture process zone ( ).

A fractional approach to strain-gradient plasticity: beyond core-radius of discrete dislocations [PDF]
arXivWe derive a strain-gradient theory for plasticity as the $\Gamma$-limit of discrete dislocation fractional energies, without the introduction of a core-radius. By using the finite horizon fractional gradient introduced by Bellido, Cueto, and Mora-Corral of 2023, we consider a nonlocal model of semi-discrete dislocations, in which the stored elastic ...
