2D-models of multilayered plates are usually derived by a discretization approach across the plate thickness. Every discretized element coincides with a homogeneous layer of the medium and basic unknowns are assumed to be temperature and/or displacement fi elds on the plate interfaces. If the number of homogeneous layers is large then the discretization approach leads to a large number of basic unknowns. In this contribution there is proposed a new approach to the 2D-modelling of heat conduction which results in 2D-model equations for only two basic unknowns, independently of the number of layers.
