Abstract
Functionally graded piezoelectric materials are of interest for a wide variety of nanotechnological applications. Buckling of functionally graded piezoelectric nanotubes, as ubiquitous event, recently attracted increasing interest. Also, in this article, the buckling response of bimorph functionally graded piezoelectric cylindrical nanoshells attended to lateral pressure is investigated on the basis of nonlocal strain gradient theory. The formulation developed on the basis of the first-order shear deformation theory with von Kármán kinematic nonlinearity. The material properties are considered to vary across thickness direction according to power law distribution. The electric potential is considered to be quadratic through thickness direction. Due to bifurcation analysis, the prebuckling deformation is initially investigated; then, in the case of simply supported edge condition, the buckling response of a bimorph functionally graded piezoelectric nanotube is studied and the influences of various parameters on buckling pressure are illustrated.
