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. © 2000 Acoustical Society of America. S0001-4966 00 01301-1

The existence of a flexural wave guided by the free edge
of a semi-infinite isotropic elastic thin plate was first demon-
