“…In recent years, numerous studies including the static, dynamic, and thermal analyses have been accomplished on micro and nanostructures (for instances, see these studies based on the nonlocal [27,28], strain gradient [29,30], modified couple stress [31,32], and non-Fourier heat conduction theories, [33,34]). Sedighi et al [35] investigated the size dependent electromechanical instability of cantilever nano-actuator by the use of the strain gradient elasticity theory. The nanoactuator was modeled by employing the Euler-Bernoulli beam theory and the equation of motion was derived via Hamilton's principle.…”
