摘要：

The transient panel flutter of a cantilevered elastic and viscoelastic strip, with one end of the strip rigidly fixed and the second end free, is investigated. It is assumed that the flow velocity vector is parallel to the plane of the strip and, with its edges, makes an angle that can take arbitrary positive and negative values. Approximate estimates of the critical flutter velocity are obtained by approximating the solution by special polynomials, by a Laplace transform with respect to time and by Bubnov's method.
