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...
