TL;DR: In this article, the Eringen strain-driven integral nonlocal elasticity model is used to analyze the free vibration, wave power transmission and reflection in multi-cracked nanorods.
Abstract: In this paper, the wave propagation method and the differential constitutive law consequent (not equivalent) to the Eringen strain-driven integral nonlocal elasticity model are utilized to analyze the free vibration, wave power transmission and reflection in multi-cracked nanorods. This aim is pursued by deriving the propagation, reflection and transmission matrices and comparing the natural frequencies obtained by these matrices with the available results in the literature. Then, the nonlocal, crack-severity, and crack location effects on the natural frequencies are presented for two combinations of the boundary conditions. Finally, the paper presents the effects that the reflected and transmitted power of a wave incident on a crack location receive from the nonlocal and crack-severity parameters. The results obtained via the reflection and transmission matrices will provide valuable insights into the subject of wave power reflection and transmission analysis in nanoscale structures for the future. The computer coding of the proposed method is much easier than the classical vibration analysis methods which makes it more appropriate in implementation.

Abstract: In this paper, the wave propagation technique is developed for analyzing the wave power reflection in circular annular nanoplates. Firstly, the propagation and reflection matrices are derived for circular annular nanoplates. Then, the obtained natural frequencies by these matrices are compared with the available literature. A set of natural frequency results is provided in a practical range of small scale for all nine possible combinations of classical boundary conditions. Finally, the effect of small scale on the reflected power of an incident wave upon different boundary conditions is investigated in details for circular annular nanoplates. The obtained hints via these matrices are valuable for future works correlated with wave power reflection and transmission in nanoscale structures.
