Abstract

The paper explores the scaling of velocity effects in ice-structure interaction, and attempts to link it to the underlying mechanics through dimensional analysis. It first examines the well-known example of flow in pipes, and uses that analogy to emphasise that too much should not be expected of scaling, and that any attempt to find a universal scaling law is likely to be doomed to disappointment. It then considers in turn the scaling of velocity effects related to inertia and gravity, to creep, and to structural compliance.
