Mechanics of Random Media as a Tool for Scale Effects in Ice Fields
The need to account for scale dependence of mechanical responses of ice fields is being noticed ever more often, e.g. (Overland et al., 1995; Dempsey, 2000). This challenge brings with it the need to study mechanics bridging different scales, and the exigency to deal with non-deterministic phenomena. In this respect, powerful tools are being offered by the fields of (i) spatio-temporal stochastic models, (ii) mechanics of random media, (iii) stochastic finite elements, and (iv) wave propagation in random media. In this paper we review some advantages offered by each of these areas as well as the possible applications they offer in mechanics of ice fields. Due to space limitations the presentation is, of necessity, brief and selective, but we hope it offers a perspective on powerful tools that exist for further research.
