This award will provide funds for the partial support of an International Union of Theoretical and Applied Mechanics (IUTAM) symposium on Scaling Laws in Ice Mechanics and Ice Dynamics, to be held in Fairbanks, Alaska, in June 2000. The IUTAM is one of the components of the International Union of Geodesy and Geophysics (IUGG), a non-governmental international scientific organization.The purpose of IUTAM symposia is to bring together researchers who have made significant contributions to the study of ice on various scales with those who have made significant contributions to the mechanics of heterogeneous media in other fields. Over the last few decades the analysis of composite materials has required the development of thermodynamic constitutive laws for materials comprised of discrete phases. These principles may be applied to sea ice when viewed as such a material, i.e. its phases being multi-year floes, thick first-year floes, and ridges in a matrix of thin first-year ice, with varying degrees of damage, i.e. cracks and leads. At this time there is no clear understanding of the range of applicability of different constitutive laws, and how the behavior of ice at small scales is linked to its behavior at geophysical scales. A major objective of the symposium is to establish an organized approach to an understanding of the scaling problem in the ice dynamics and ice mechanics community through the exchange of ideas with leaders in the heterogeneous materials research community.

该奖项将为国际理论与应用力学联合会（IUTAM）将于2000年6月在阿拉斯加州费尔班克斯举行的冰力学和冰动力学标度定律研讨会提供部分支持资金。 国际大地测量学和地球物理学联合会是一个非政府国际科学组织，其组成部分之一，国际大地测量学和地球物理学联合会专题讨论会的目的是将在各种尺度上对冰的研究作出重大贡献的研究人员与在其他领域对非均匀介质力学作出重大贡献的研究人员聚集在一起。 在过去的几十年里，复合材料的分析需要发展由离散相组成的材料的热力学本构关系。 这些原则可以适用于海冰，如果把它看作是这样一种物质，即它的阶段是多年浮冰、第一年厚浮冰和第一年薄冰基质中的脊，并有不同程度的损坏，即裂缝和裂缝。 目前，对于不同本构关系的适用范围，以及冰在小尺度下的行为如何与其在地球物理尺度下的行为联系起来，还没有明确的认识。 研讨会的一个主要目标是建立一个有组织的方法，通过与异质材料研究界的领导人交流思想，了解冰动力学和冰力学界的缩放问题。
