The panel is a laminate of piezoelectric material perfectly bonded to the convex and concave surfaces of a core of passive material. Since the curved edges are free and the straight edges are pinned a fixed distance apart, the response of the panel is independent of the axial coordinate. Hence, the governing ordinary differential equations are of the same form as for a shallow circular arch. Without induced strain actuation, the panel exhibits snap-through behavior under the midspan load. Induced strain distributions are determined at a constant midspan load to displace the panel to an inverted configuration in a stable manner. This adaptive structure may find application as an electromechanical, nonlinear spring with a digital-like, load-displacement response characteristic.ix, 99 leavesBTDapplication/pdfenIn Copyrightshallowarchpanelpiezoelectricsnap-throughLD5655.V855 1996.S5464Equilibrium of a shallow arch subjected to PZT actuators and a deadweight loadThesishttp://scholar.lib.vt.edu/theses/available/etd-12172008-063435/
