Flutter of infinitely long plates and shells. I - Plate
The aeroelastic stability of an infinitely long panel of finite width with the upper surface exposed to an in viscid flow is examined. The panel behavior is accounted for by small deflection plate theory, whereas the aerodynamic forces acting on the panel are described by the classical linearized, potential theory. The panel is assumed to be simply supported along the side edges, although other edge conditions may be considered in a similar manner (e.g., clamped edges). Rather extensive numerical results have been obtained for flutter velocity (and dynamic pressure) indicating the effects of Mach number, air/panel mass ratio, and viscous structural damping. A comparison of the present results with those obtained by previous investigators for a long, narrow panel (using a more elaborate method that accounts for the finite length) shows some discrepancy between the two results. © 1966 American Institute of Aeronautics and Astronautics, Inc., All rights reserved.
