On the dynamic behaviour of uniperiodic plates made of orthotropic elements

The aim of this contribution is to propose a new non-asymptotic 2D-model of non-homogeneous Reissner type elastic plates with one-directional periodic (uniperiodic) structure. This model was obtained by tolerance averaging technique (TAA) describing effect of repetitive cell size l (and at the same time the period-length of in-homogeneity) on the overall plate behaviour. The new feature of the proposed model is the possibility to apply the analysis of plates having thickness of an order of the period-length. So far, the non-asymptotic 2Dmodel of Reissner-type uniperiodic plates was formulated under assumption that the plate thickness is very small compared to the period-length.
