The review discusses the state of thinking of each of the main national groups investigating sea ice and gives an overall appraisal of the field as a whole. Emphasis is placed on (1) the physical basis for interpreting sea ice strength (phase relations, air volume, and structural considerations), (2) theoretical considerations (strength models, air bubbles and salt reinforcement, and interrelations between growth conditions and strength), (3) experimental results (tensile, flexural, shear, and compressive strength, elastic modulus, shear modulus and Poisson's ratio, time dependent effects, and creep), and (4) plate characteristics. The paper includes a review of problems in sea ice investigations, relates the chemical, crystallographic, mechanical, and physical aspects involved, and concludes by showing how to utilize this knowledge to solve practical problems.

The first part of the report provides an introduction to the mechanics of deformable solids, covering the basic ideas of stress and strain, rheology, equilibrium equations, strain/displacement relations, constitutive equations, and failure criteria. Fracture mechanics and fracture toughness are also reviewed briefly. The second part summarizes available data on the mechanical properties of freshwater ice and saline ice, accounting for the influences of strain rate and loading rate, temperature, porosity, salinity, and grain size. Boundary value problems are not dealt with, but there is discussion of some miscellaneous topics, including thermal strains, behavior of brash ice, and pressure ridges. The report was written as a study text for a NATO Advanced Study Institute on Sea/Ice/Air Interactions, and was intended to be used in conjunction with companion texts on related topics. This report was written during the summer of 1981, and thus does not cover all results which appeared after the end of 1981.

A phenomenological approach must be followed in studying the mechanical behavior of sea ice. The material should be first studied at the level of the solid continuum before considering the behavioral contributions from defects and impurities in the structure as well as grain boundary interference. Experimental evidence suggests that the mechanical behavior of sea ice is quite similar to other solids at near-melting temperature. A reasonable starting point for developing constitutive equations for the mechanical behavior of sea ice would be the fundamental theories advanced in the research of metals at elevated temperatures. In some areas, the advanced theory appears to be adaptable to the study of mechanical behavior of sea ice, while in others, constitutive equations will have to be developed. Emphasis is needed in researching the problems of short-term behavior, long-time creep and parametric effects of temperature, age and brine content on strength, as well as repeated loading and cumulative damage. A major effort is needed to develop basic data on behavior of sea ice in simple bending and bending under 2- and possibly 3-dimensional states of stress. This includes investigation of mechanical behavior of small beams, model ice sheets, and the in situ condition. (Author).
