A CURRENT VIEW ON SEA ICE MODELLING

A brief history of the development of ice modeling techniques emhasizing the various types of model ice is given. A comparison is then made of the values of the physical properties of model ice as against actual sea ice. For a typical model test, in which the geometric scale factor equals 30, the mechanical properties of all of the different model ices are tabulated. For many of these ices, data have not been published. It is shown that only columnar grained ice can correctly model situations where compression is important. Some current concerns of ice modeling are discussed, but lack of good quality full-scale data makes an objective comparison between model and full-scale ice difficult.
