The Effect of a Nonlocal Thermoelastic Model on a Thermoelastic Material under Fractional Time Derivatives

Fractal and Fractional, 2022
This article develops a novel nonlocal theory of generalized thermoelastic material based on fractional time derivatives and Eringen’s nonlocal thermoelasticity. An ultra-short pulse laser heats the surface of the medium’s surrounding plane.

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

Advances 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.

The Cauchy Problem for a One Dimensional Nonlinear Peridynamic Model [PDF]

, 2008
This paper studies the Cauchy problem for a one-dimensional nonlinear peridynamic model describing the dynamic response of an infinitely long elastic bar. The issues of local well-posedness and smoothness of the solutions are discussed.

Influence of the nonlocal parameter on the transverse vibration of double-walled carbon nanotubes [PDF]

, 2015
A high-order nonlocal continuum beam model is proposed, which can be applied to study the transverse vibrations of double-walled carbon nanotubes (DWCNTs), including those that could have initial deformations due to defects or external actions.

Soft random solids and their heterogeneous elasticity [PDF]

, 2009
Spatial heterogeneity in the elastic properties of soft random solids is examined via vulcanization theory. The spatial heterogeneity in the \emph{structure} of soft random solids is a result of the fluctuations locked-in at their synthesis, which also ...
