On Dislocations in a Special Class of Generalized Elasticity

, 2005
In this paper we consider and compare special classes of static theories of gradient elasticity, nonlocal elasticity, gradient micropolar elasticity and nonlocal micropolar elasticity with only one gradient coefficient.

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.

Extension the Noether's theorem to Lagrangian formulation with nonlocality

, 2012
A Lagrangian formulation with nonlocality is investigated in this paper. The nonlocality of the Lagrangian is introduced by a new nonlocal argument that is defined as a nonlocal residual satisfying the zero mean condition.

Thermodynamically consistent gradient elasticity with an internal variable

, 2020
The role of thermodynamics in continuum mechanics and the derivation of the proper constitutive relations is a discussed subject of Rational Mechanics. The classical literature did not use the accumulated knowledge of thermostatics and was very critical ...

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 ...
