Elastostatics of Bernoulli–Euler Beams Resting on Displacement-Driven Nonlocal Foundation

open access: yesNanomaterials, 2021
The simplest elasticity model of the foundation underlying a slender beam under flexure was conceived by Winkler, requiring local proportionality between soil reactions and beam deflection.

On the numerical solution of some differential equations with nonlocal integral boundary conditions via Haar wavelet [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2022
Differential equations with nonlocal boundary conditions are used to model a number of physical phenomena encountered in situations where data on the boundary cannot be measured directly. This study explores numerical solutions to elliptic, parabolic and

Relations between Spectrum Curves of Discrete Sturm-Liouville Problem with Nonlocal Boundary Conditions and Graph Theory. II

open access: yesLietuvos Matematikos Rinkinys, 2021
In this paper, relations between discrete Sturm--Liouville problem with nonlocal integral boundary condition characteristics (poles, critical points, spectrum curves) and graphs characteristics (vertices, edges and faces) were found. The previous article

Nonlocal boundary value problem in terms of flow for Sturm-Liouville operator in differential and difference statements [PDF]

open access: yesE-Journal of Analysis and Applied Mathematics, 2019
Sturm-Liouville operator with second kind of nonlocal boundary value conditions is considered. For the classical solution, a priori estimate is established and unique existence is proved.

Closed-Form Solution of the Bending Two-Phase Integral Model of Euler-Bernoulli Nanobeams

open access: yesAlgorithms, 2022
Recent developments have shown that the widely used simplified differential model of Eringen’s nonlocal elasticity in nanobeam analysis is not equivalent to the corresponding and initially proposed integral models, the pure integral model and the two ...

A four-point nonlocal integral boundary value problem for fractional differential equations of arbitrary order

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2011
This paper studies a nonlinear fractional differential equation of an arbitrary order with four-point nonlocal integral boundary conditions. Some existence results are obtained by applying standard fixed point theorems and Leray-Schauder degree theory ...
