This paper presents a problem of vibrations of thin functionally graded plates. To describe this kind of plates three averaged models are proposed: a tolerance model, an asymptotic model and a combined asymptotictolerance model, cf. [10]. Calculational results obtained for a functionally graded plate band using the proposed models are compared to each other.

In this note there are considered functionally graded plates. To describe vibrations of these plates and take into account the effect of the microstructure, the tolerance averaging method is applied, cf. [7, 8]. There are formulated governing equations of the asymptotic-tolerance model, cf. [8]. Calculational results obtained for a functionally graded plate band using the proposed model, are compared to results by the known – tolerance and asymptotic models.
