A NONLOCAL THEORY FOR BRITTLE FRACTURE

open access: yes, 1991
In this paper,a nonlocal theory of fracture for brittle materials has been systematically devel-oped,which is composed of the nonlocal elastic stress fields of Griffith cracks of mode-Ⅰ,Ⅱ and Ⅲ,theasymptotic forms of the stress fields at the neighborhood

A nonlocal sinusoidal shear deformation beam theory with application to bending, buckling, and vibration of nanobeams [PDF]

open access: yes, 2012
This paper presents a nonlocal sinusoidal shear deformation beam theory for the bending, buckling, and vibration of nanobeams. The present model is capable of capturing both small scale effect and transverse shear deformation effects of nanobeams, and ...

Nonlocal elastic compliance for soft solids: Theory, simulations, and experiments [PDF]

open access: yesPhysical Review E, 2008
The nonlocal elastic response function is crucial for understanding many properties of soft solids. This may be obtained by measuring strain-strain autocorrelation functions. We use computer simulations as well as video microscopy data of superparamagnetic colloids to obtain these correlations for two-dimensional triangular solids.

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

open access: yesFractal 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.

Nonlocal theory of curved rods. 2-D, high order, Timoshenko’s and Euler-Bernoulli models

open access: yesCurved and Layered Structures, 2017
New models for plane curved rods based on linear nonlocal theory of elasticity have been developed. The 2-D theory is developed from general 2-D equations of linear nonlocal elasticity using a special curvilinear system of coordinates related to the ...
