A computational aeroelastic model is presented for a cantilevered plate rotated from a position with the clamped edge normal to the flow (0 deg) to where the clamped edge is aligned with the flow (90 deg) using a new inextensible plate theory. A large-amplitude limit-cycle oscillation has been observed beyond the linear flutter speed in both the computations and in a wind-tunnel experiment. The computations and experiments for the limit-cycle oscillation response of the several yawed plate aeroelastic models show that the inextensible plate theory produces results in good agreement with the measurements. Also, a comparison with results obtained using von Kármán's nonlinear plate theory has been made.
