AbstractThis paper provides the complete set of equations for the practical elastic moduli for polycrystalline ice (Young's modulus, shear modulus, and Poisson's ratio). These equations are needed to calculate the elastic strains generated in ice during loading. For columnar grained ice (anisotropic ice). Sinha (1989) formulated equations for Young's modulus and shear modulus. In this paper, new equations for Poisson's ratio are proposed. Three averaging methods are used to derive equations for the practical elastic moduli for granular ice (isotropic ice). The equations are used to predict the values of both Young's modulus and Poisson's ratio, and then the predictions are compared to some experimental data. The objective is to assess which averaging method is appropriate for polycrystalline ice.
