Vestn. Mosk. Univ., Ser. I 2005, No. 1, 68-71 (2005); translation in Mosc. Univ. Mech. Bull. 60, No. 1, 27-30 (2005).
The paper deals with a problem on a flutter of a rectangular plate being a part of a thin wedge surface. Critical velocity of flow is determined for various values of parameters. The results are compared with those obtained in terms of linear piston theory. New mechanical effects are discovered.
