Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

A non-local Euler-Bernoulli nanobeam theory is used to calculate free vibrations for a beam resting on a Winkler/Pasternak-type elastic foundation. On using Hamilton's Principle, the nonlinear equation of motion, which includes terms for stretching of the neutral axis, is derived. The Adomian modified decomposition method is applied to solve the fourth-order governing equation. Investigations are made of the effects on the vibrations of the non-local parameter, the Winkler and Pasternak parameters, in addition to the effects of applying simple-simple and clamped-clamped boundary conditions.
