Abstract: Recent research has shown that the structure of an ice sheet can display regions of distinct mechanical response consistent with its natural development. In this paper, we examine a simplified model for the behaviour of an ice sheet in which the primary ice layer is modelled as an isotropic elastic plate and the secondary columnar-grained ice layer is modelled as a Pasternak-Vlazov type elastic layer which possesses only shear interaction. An approximate solution of the composite plate flexure is established by adopting a Rayleigh-Ritz type variational method. Computed numerical results have shown good correlation between the two techniques. The latter technique represents a particularly simple approach to the analysis of floating composite plates.
