Comment on "Green's Function and Receptance for Structures Consisting of Beams and Plates"
I N his recent article, Kelkel uses the receptance method and the method of superposition to determine the Green's function for vibrating beam-stiffened rectangular plates with free edges, thus facilitating the computation of the natural frequencies of such structures. We are somewhat alarmed by the author's failure to reference the substantial body of prior work in the area of free vibration analysis of beamstiffened plates. In particular, a similar article by Nicholson appeared in this journal 18 months prior to KelkePs. Neither Nicholson nor any of the references therein were cited.
