Analysis of a micro piezoelectric vibration energy harvester by nonlocal elasticity theory

open access: yesAdvances in Mechanical Engineering, 2016
A theoretical model of a micro piezoelectric energy harvester is proposed based on the nonlocal elasticity theory, which is operated in the flexural mode for scavenging ambient vibration energy.

Nonlinear Wave Modulation in Nanorods Using Nonlocal Elasticity Theory

open access: yesInternational Journal of Nonlinear Sciences and Numerical Simulation, 2018
Abstract In this study, nonlinear wave modulation in nanorods is examined on the basis of nonlocal elasticity theory. Eringen's nonlocal elasticity theory is employed to derive nonlinear equations for the motion of nanorods. The analysis of the modulation of axial waves in nonlocal elastic media is performed, and the reductive ...

Chaos prediction in nano-resonators based on nonlocal elasticity theory

open access: yesMATEC Web of Conferences, 2018
By decreasing the thickness of micro- and nano- beams, classical continuum theory is not accurate to predict the static and dynamic response due to the absence of length scale parameter.

A general theory of nonlocal elasticity based on nonlocal gradients and connections with Eringen's model

open access: yes
We develop a general theory of nonlocal linear elasticity based on nonlocal gradients with general radial kernels. Starting from a nonlocal hyperelastic energy functional, we perform a formal linearization around the identity deformation to obtain a system of nonlocal linear elasticity equations.

Theory of Nonlocal Elasticity for Plate Structures

open access: yes
The thesis explores size-dependent continuum mechanics in plate structures. Assuming a power-law distribution, the study includes functionally graded materials where the material properties are changed through the thickness. First, the nonlocal stress-driven theory with a bi-exponential kernel is introduced for thin plates based on the Kirchhoff ...

Completing Eringen’s nonlocal elasticity theory and its connection with surface elasticity

open access: yesInternational Journal of Engineering Science
Eringen’s nonlocal elasticity theory is known to suffer from boundary-related inconsistencies, which arise from the presence of additional Boundary Conditions, commonly referred to as Constitutive (CBCs), which are embedded in the Green’s function-type attenuation functions and supplement the problem BCs.

Young measures in a nonlocal phase transition problem [PDF]

open access: yes, 1997
A nonlocal variational problem modelling phase transitions is studied in the framework of Young measures. The existence of global minimisers among functions with internal layers on an infinite tube is proved by combining a weak convergence result ...

Nonlocal strong forms of thin plate, gradient elasticity, magneto-electro-elasticity and phase field fracture by nonlocal operator method [PDF]

open access: yes, 2021
The derivation of nonlocal strong forms for many physical problems remains cumbersome in traditional methods. In this paper, we apply the variational principle/weighted residual method based on nonlocal operator method for the derivation of nonlocal ...
