In this work, nonlocal vibration of double of carbon nanotubes (CNTs) system conveying fluid coupled by visco-Pasternak medium is carried out based on nonlocal elasticity theory where CNTs are placed in uniform temperature change and magnetic field. Considering Euler-Bernoulli beam (EBB) model and Knudsen number, the governing equations of motion are discretized and Ritz method is applied to ob...

The wave propagation in viscothermoelastic materials is discussed the present work using nonlocal thermoelasticity model. This model was created Lord and Shulman generalized thermoelastic due to consequences of delay times formulations heat conduction motion equations. Eringen’s theory continuum. linear Kelvin–Voigt viscoelasticity explains viscoelastic properties isotropic material. analytical...

Classical nonlocal field models consisting of probability density functionals over functions defined everywhere on Minkowski space are constructed directly from a quantum field state, using functional methods.

We investigate the effects of hydrodynamic nonlocal response in hyperbolic metamaterials (HMMs), focusing on the experimentally realizable parameter regime where unit cells are much smaller than an optical wavelength but much larger than the wavelengths of the longitudinal pressure waves of the free-electron plasma in the metal constituents. We derive the nonlocal corrections to the effective m...

In the field of Civil Engineering, Knowledge Engineering techniques have been applied to safety evaluation, damage assessment and design of structures, but applications are usually limited to specific cases . In this paper, a general approach to structural mechanic problems, based on Qualitative Physics, is discussed, providing the way to model and reason about a wide class of structures as phy...

Abstract In this contribution, we present a novel approach on how to treat material interfaces in nonlocal models based peridynamics (PD) and particular continuum‐kinematics‐inspired (CPD), variationally consistent peridynamic formulation. Our method relies interface where the subdomains overlap. Within region, kinematic coupling of two constituents is enforced. The contact purely geometrical a...

A sphere of a ferrogel is exposed to a homogeneous magnetic field. In accordance to theoretical predictions, it gets elongated along the field lines. The time dependence of the elastic shear modulus causes the elongation to increase with time, similar to mechanic creep experiments, and the rapid excitation causes the sphere to vibrate. Both phenomena can be well described by a damped harmonic o...
