This paper presents a discussion about the results of  the article on the vibration of angle-ply symmetric laminated composite rectangular plates with edges elastically restrained, by  Ashour [1]. The same problem is treated but with the application of the Ritz method with  orthogonal polynomials  as coordinate functions. The existence of some inconsistencies in Ref.[1] is demonstrated.  New numerical results for the described plates are included.
