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 ...

On nonlinear dilatational strain gradient elasticity [PDF]
Continuum Mechanics and Thermodynamics, 2021 AbstractWe call nonlinear dilatational strain gradient elasticity the theory in which the specific class of dilatational second gradient continua is considered: those whose deformation energy depends, in an objective way, on the gradient of placement and on the gradient of the determinant of the gradient of placement.

Generation of imprinted strain gradients for spintronics
Applied Physics Letters, 2023 In this work, we propose and evaluate an inexpensive and CMOS-compatible method to locally apply strain on a Si/SiOx substrate. Due to high growth temperatures and different thermal expansion coefficients, a SiN passivation layer exerts a compressive stress when deposited on a commercial silicon wafer.

Cellular Orientation Is Guided by Strain Gradients [PDF]
Integrative Biology, 2016 The strain-induced reorientation response of cyclically stretched cells has been well characterized in uniform strain fields. In the present study, we comprehensively analyse the behaviour of human fibroblasts subjected to a highly non-uniform strain field within a polymethylsiloxane microdevice.

On fracture in finite strain gradient plasticity [PDF]
International Journal of Plasticity, 2016 In this work a general framework for damage and fracture assessment including the effect of strain gradients is provided. Both mechanism-based and phenomenological strain gradient plasticity (SGP) theories are implemented numerically using finite deformation theory and crack tip fields are investigated.

Bicrystals with Strain Gradient Effects [PDF]
MRS Proceedings, 1996 ABSTRACTThe boundary between two perfectly bonded single crystals plays a very important role in determining the deformation of the bicrystal. This work addresses the role of the grain boundary by considering the elevated hardening of a slip system due to a slip gradient.

On the strain gradient bending deformations [PDF]
Journal of the Mechanical Behaviour of Materials, 2013 AbstractBending deformations are reviewed in the context of strain gradient linear elasticity, considering the complete set of strain gradient components. It is well understood that conventional bending deformations depend on the collective uniaxial extension of axial fibers resulting in the dependence on the curvature of the neutral geometry of ...

Irreducible decomposition of strain gradient tensor in isotropic strain gradient elasticity [PDF]
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2016 In isotropic strain gradient elasticity, we decompose the strain gradient tensor into its irreducible pieces under the n‐dimensional orthogonal group . Using the Young tableau method for traceless tensors, four irreducible pieces (), which are canonical, are obtained.

On a strain gradient theory of thermoviscoelasticity
Mechanics Research Communications, 2013 This paper is concerned with a strain gradient theory of thermoviscoelasticity in which the time derivatives of the strain tensors are included in the set of independent constitutive variables. The theory is motivated by the recent interest in the study of gradient theories.
