Surface and nonlocal effects in piezoelectric nanobeams

This study investigates the electromechanical behavior of piezoelectric nanobeams using a nonlocal surface stress-driven elasticity model. The governing equations are derived through Hamilton's principle. The effects of the nonlocal parameter, external electric voltage and surface energy on the static and dynamic responses of Simply-Supported and Clamped-Clamped piezoelectric nanobeams are analyzed and discussed. The findings demonstrate how the proposed approach can aid in the development of advanced devices based on modern piezoelectric nanobeams.
