A meshless collocation method for band structure simulation of nanoscale phononic crystals based on nonlocal elasticity theory

Journal of Computational Physics, 2020
In this paper, the band structures of nanoscale phononic crystals based on the nonlocal elasticity theory are calculated by using a meshfree local radial basis function collocation method (LRBFCM). The direct method is applied to enhance the stability of

Nonlocal polar elastic continua

International Journal of Engineering Science, 1972
Abstract A continuum theory of nonlocal polar bodies is developed. Both the micromorphic and the non-polar continuum theories are incorporated. The balance laws and jump conditions are given. By use of nonlocal thermodynamics and invariance under rigid motions, constitutive equations are obtained for the nonlinear micromorphic elastic solids.

Waves in dual-phase-lag thermoelastic materials with voids based on Eringen’s nonlocal elasticity

Journal of thermal stresses, 2019
The main idea of the present work is to extend Eringen’s theory of nonlocal elasticity to generalized thermoelasticity with dual-phase-lag and voids.

Stress-driven nonlocal elasticity for the instability analysis of fluid-conveying C-BN hybrid-nanotube in a magneto-thermal environment

Physica Scripta, 2020
The Eringen’s strain-driven nonlocal differential model is well-established to exhibit inconsistencies when applied to bounded continua of applicative interest.

Contribution of nonlocal interactions to DNA elasticity

The Journal of Chemical Physics, 2011
A nonlocal harmonic elastic rod model is proposed to describe the elastic behavior of short DNA molecules. We show that the nonlocal interactions contribute to effective bending energy of the molecule and affect its apparent persistence length.

Wave propagation in fractional nonlocal elastic continua

IFAC Proceedings Volumes, 2013
In this paper, the wave propagation in one-dimensional elastic continua, characterized by nonlocal interactions, is investigated by means of a fractional calculus approach. Derivatives of a non-integer order 1 < a < 2 with respect to the spatial variable are involved in the governing equation.
