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 pre dicted in 1960 by Yu K. Konenkov using Kirchhoff plate theory. It is demons trated that the flexural edge wave is also predicted by Mindlin's plate the ory, and that the prediction agrees with measured data. It is noted that th e edge wave was erroneously presented as a new type of bending wave solutio n in a recently published paper in this journal. (C) 2000 Acoustical Societ y of America.
