Flexural edge waves and comments on 'a new bending wave solution for the classical plate equation' [J. Acoust. Soc. Am. 104, 2220-2222 (1998)]

A brief review is presented of the theory of flexural edge waves, first predicted in 1960 by Yu K. Konenkov using Kirchhoff plate theory. It is demonstrated that the flexural edge wave is also predicted by Mindlin's plate theory, and that the prediction agrees with measured data. It is noted that the edge wave was erroneously presented as a new type of bending wave solution in a recently published paper in this journal. (C) 2000 Acoustical Society of America.
