Abstract: Physics of sea ice has now advanced to the point that one can predict composite properties of sea ice sheets on a rational basis.This leads to a synthesis on the basis of past analysis.For practical purposes nomograms or computer techniques can be developed, with easily measured quantities as input.The foundation for such methods is laid in this paper.The composite properties discussed are: zero strength and deformation layer, neutral layer, average crushing strength and Young's modulus, calculation of zero, first and second order moments, modulus of inertia, section modulus, flexural strength, plate rigidity, action radius as well as failure mechanism.The principal assumption underlying the future construction of nomograms from equations is a linear temperature profile and constant salinity.For computer techniques a more flexible polynomial approach is suggested.The basical physical parameter invariably is the brine volume which can be calculated from temperature and salinity.Only surface temperature could be used under simplifying assumptions, but profile data at least for four points are suggested for computer techniques.Comparison with test data is now proceeding."
