چکیده مقاله

In this study, effects of nonlocal parameter and von Kàrmàn geometric nonlinearity on the vibration behavior of a single-walled boron nitride nanotube (SWBNNT) is investigated based on the nonlocal piezoelasticity theory [1]. The SWBNNT is considered as a nanobeam within the framework of the Euler–Bernoulli beam (EBB). According to Figure 1, loading is composed of a temperature change and an imposed axially electric potential throughout the SWBNNT [2]. The interactions between the SWBNNT and its surrounding elastic medium are simulated by Winkler and Pasternak foundation models as follows [3]:
