Irreducible decomposition of strain gradient tensor in isotropic strain gradient elasticity [PDF]

open access: yesZAMM - 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.

Higher order nonlocal strain gradient approach for wave characteristics of carbon nanorod

open access: yesNonlinear Analysis, 2014
In this paper an attempt is made to study the wave dispersion characteristics of a carbon nanorod through second, fourth, sixth and eighth order nonlocal strain gradient models. Expressions are derived for both wave number and wave speeds of the nanorod.

On Representing Strain Gradient Elastic Solutions of Boundary Value Problems by Encompassing the Classical Elastic Solution

open access: yesMathematics, 2022
The present work aims to primarily provide a general representation of the solution of the simplified elastostatics version of Mindlin’s Form II first-strain gradient elastic theory, which converges to the solution of the corresponding classical elastic ...

Cellular Orientation Is Guided by Strain Gradients [PDF]

open access: yesIntegrative 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.

Nonsingular stress and strain fields of dislocations and disclinations in first strain gradient elasticity

open access: yes, 2005
The aim of this paper is to study the elastic stress and strain fields of dislocations and disclinations in the framework of Mindlin's gradient elasticity.

Pseudo Jahn-Teller Effect In The Origin Of Enhanced Flexoelectricity [PDF]

open access: yes, 2015
The controversy between the theory and experiment in explaining the origin of enhanced flexoelectricity is removed by taking into account the pseudo Jahn-Teller effect (PJTE) which, under certain conditions, creates local dipolar distortions of dynamic ...

Nonlocal-Strain-Gradient-Based Anisotropic Elastic Shell Model for Vibrational Analysis of Single-Walled Carbon Nanotubes

open access: yesC
In this study, a new anisotropic elastic shell model with a nonlocal strain gradient is developed to investigate the vibrations of simply supported single-walled carbon nanotubes (SWCNTs).

Perspective on hetero-deformation induced (HDI) hardening and back stress

open access: yesMaterials Research Letters, 2019
Heterostructured materials have been reported as a new class of materials with superior mechanical properties, which was attributed to the development of back stress.

Electric force microscopy of induced charges and surface potentials in GaN modified by light and strain [PDF]

open access: yes, 1999
We have studied molecular beam epitaxy grown GaN films using electric force microscopy to detect sub-1 µm regions of electric field gradient and surface potential variations associated with GaN extended defects.
