Abstract:Piezoelectric nanobeams with excellent mechanical, thermal and electrical properties are important components in micro-nano electromechanical systems, which are widely used as sensors, brakes and resonators. Based on the Euler-Bernoulli beam model, the influence of surface effect on the post-buckling behavior of piezoelectric nanobeams is analyzed. According to the surface elasticity theory and the ' core-shell ' model, the surface energy model is used to introduce the influence of surface effect. The governin… Show more
