Abstract

A thin piezoelectric layer, bonded on a plane rigid support up to an initial circular defect of adhesion, is considered. The piezoelectric layer is actuated by an applied transversal difference of electric potential, which may induce a buckling of the debonded zone. The post-buckling behaviour is studied by using a suitable generalization of the von Karman geometrically nonlinear plate theory. The quasi-static delamination process induced by the buckling phenomenon is investigated via the classical Griffith-Irwin energy criterion.
