摘要：
The ability of the one-site self-consistent scheme to model the behaviour of polycrystalline ice is assessed by studying the particular case of a two-dimensional polycrystal which represents natural S2-columnar ice. The self-consistent analysis is carried out analytically and its results are compared dth finite-element computations. Despite a weak representation of the interaction between a grain and its surroundings, due to the strong anisotropy of the ice crystal, the resulting macroscopic behaviour is found to be acceptable.
