MECHANICAL PROPERTIES OF SEA ICE AS THEY INFLUENCE DESIGN CONSIDERATIONS

The recent expansion of industrial development in Arctic climates has been so rapid as to exceed the growth rate anticipated by researchers seeking to understand the interactions among such physical parameters as water, ice, soil and temperature. Each of these parameters possesses wide variability, and their overall balance in nature at a given location may be fragile. Designs for offshore structures, pipelines, roads, etc. must be engineered so as to produce the least disturbance to the natural environment. For offshore structures it becomes increasingly important to understand and make allowance for the behavior of sea ice as another form of external loading. The author reviews the crystal structure of sea ice and brings together the available quantiative data on tensile, flexural, shear, and compressive strengths. The effects of rates of loading and viscoelastic behavior on stresses are also discussed.
