This three-year award supports U.S.-France cooperative research in mechanics of materials between Erland M. Schulson at the Ice Research Laboratory, Dartmouth College, and Jerome Weiss at the Laboratory for Glaciology and Geophysics of the Environment, French National Center for Scientific Research, Grenoble, France. They propose to perform experimental studies on the nucleation of cracks in ice under multiaxial compression. The experiments will include investigations of the distinction between the effects of confinement and loading and the effects of microstructure. The work will contribute to our understanding of the fracture of ice and to our general understanding of fracture in other brittle materials. The project takes advantage a `model` ice developed by the French laboratory using unique techniques for controlling microstructure.

这个为期三年的奖项支持美国-法国材料力学合作研究。Schulson在达特茅斯学院冰研究实验室，杰罗姆韦斯在法国格勒诺布尔法国国家科学研究中心冰川学和环境地球物理实验室。 他们建议对多轴压缩下冰中裂纹的成核进行实验研究。 实验将包括调查约束和加载的影响和微观结构的影响之间的区别。 这项工作将有助于我们理解冰的断裂和我们的一般理解在其他脆性材料的断裂。 该项目利用了法国实验室利用独特的微观结构控制技术开发的“模型”冰。
