SIZE-DEPENDENT PIEZOELECTRICITY AND ELASTICITY DUE TO THE ELECTRIC FIELD-STRAIN GRADIENT COUPLING AND STRAIN GRADIENT ELASTICITY

International Journal of Applied Mechanics, 2013
A size-dependent nonclassical Bernoulli–Euler beam model based on the strain gradient elasticity is proposed for piezoelectric nanowires. The governing equations and the corresponding boundary conditions are naturally derived from the variational principle.

ON NONLOCAL LAM STRAIN GRADIENT MECHANICS OF ELASTIC RODS

International Journal for Multiscale Computational Engineering, 2020
Numerous contributions can be found in the recent literature exploiting the nonlocal strain gradient model, introduced in consequence of unification of the differential relation (consequent but not equivalent to Eringen nonlocal integral law) and strain gradient elasticity.

Symmetry conditions in strain gradient elasticity

Mathematics and Mechanics of Solids, 2015
We study the variational significance of the “order-of-differentiation” symmetry condition of strain gradient elasticity. This symmetry condition stems from the fact that in strain gradient elasticity, one can interchange the order of differentiation in the components of the second displacement gradient tensor.

Vibrations of lattice nanobeams in strain gradient elasticity

European Journal of Mechanics - A/Solids
This study investigates vibrations of nanoscale structures using a novel finite element method based on {the theory of the strain gradient elasticity}. {The governing equations are derived from the Euler–Bernoulli beam theory enhanced with Eringen’s strain gradient formulation to capture the axial and bending behavior with nonlocal effects.

The Eigenmodes in Isotropic Strain Gradient Elasticity

2016
We present the spectral decomposition of the isotropic stiffness hexadic that appears in Mindlin’s strain gradient elasticity, where the kinematic variable is the second gradient of the displacement field. It turns out that four distinct eigenmodes appear, two of which are universal for all isotropic strain gradient materials, and two depend on an ...
