Abstract

Piezoelectric nanofilms (PNFs) are often subject to compression in their applications. Bulking thus occurs for those with a thin thickness. In this paper we have conducted a comprehensive study of the bucking behaviors of PNFs which are treated as sandwich-plates to account for the effect of the sur...

Abstract: Piezoelectric nanofilms (PNFs) are often subject to compression in their applications. Bulking thus occurs for those with a thin thickness. In this paper we have conducted a comprehensive study of the bucking behaviors of PNFs which are treated as sandwich-plates to account for the effect of the surface elasticity and piezoelectricity. The results from the analytic formulae show that the surface and piezoelectric effects influence not only the critical buckling load but also the associated modes. Specifically the two effects depend strongly on the nature of the residual surface stress and the direction of the voltage applied on PNFs.
