ABSTRACT
In this note free vibrations of a plate band with a smooth and a slow gradation of macroscopic properties called a transversally graded plate band have been analysed. In this contribution the tolerance and the asymptotic models of these bands have been presented. Then, these models have been used to calculate fundamental free vibrations frequencies of the plate band, by means of the Ritz method. Moreover, these results have been compared to results obtained by a computer programm of the finite element method (FEM).
Key words: thin plate band, transversally graded structure, free vibrations.
