Wave reflection in semiconductor nanostructures

Theoretical and Applied Mechanics Letters, 2018
: Based on nonlocal thermoelastic theory, this article studies the reflection of waves in nanometer semi-conductor media. Firstly, the governing equations are established based on coupled nonlocal elasticity theory, plasma diffusion equation, and moving ...

Nonlocal postbuckling analysis of graphene sheets with initial imperfection based on first order shear deformation theory

Results in Physics, 2017
In this paper, the first order shear deformation theory (FSDT) is used to investigate the postbuckling behavior of orthotropic single-layered graphene sheet (SLGS) under in-plane loadings.

A nonlocal continuum theory for diatomic elastic solids

International Journal of Engineering Science, 1977
Abstract In this study, taking the effects of long range intermolecular forces into account, a mechanical model for diatomic solids is presented. The model we use is based upon the assumption that a diatomic solid may be considered to consist of two simple elastically interacting media which are initially overlapping but may have relative motions at ...

A Unifying Approach to Self‐Organizing Systems Interacting via Conservation Laws

Advanced Intelligent Discovery, EarlyView.
The article develops a unified way to model and analyze self‐organizing systems whose interactions are constrained by conservation laws. It represents physical/biological/engineered networks as graphs and builds projection operators (from incidence/cycle structure) that enforce those constraints and decompose network variables into constrained versus ...
