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

The self-sustained oscillations of functionally graded nanotubes reinforced composite thin-walled structures are treated with account of geometrical nonlinearity. The Reddy shear deformation theory is used in this analysis. The system of the nonlinear dynamical system is derived by assumed-mode method to study the structure dynamic instability and the self-sustained vibrations. The self-sustained oscillations take place due to the Hopf bifurcation. The self-sustained oscillations are calculated by the harmonic balance method.
