多年氷の変形様式と応力伝達について

In this paper, we presents the results of calculations to examine the role of variable thickness in limiting the strength of multiyear ice floe.We model a multiyear Ice floe with bottom roughness both in the form of sine curve and in two beam sections of variable thicknesses with/without an elastic foundation.It is shown that the roughness amplitude and thickness of the floe over which compressive loads are applied to the boundary are the most important variables in determining the force which can be transmitted through the floe to an offshore structure in Arctic waters.
