This three-year award supports U.S.-France cooperative research in solid mechanics between Xanthippi Markenscoff of the University of California in San Diego and Helmut Kirchner of the Institute of Materials Science at the University of Paris (South). The objective of their research is to develop a mathematical model which addresses dislocation effects in fracture mechanics. Dr. Markenscoff brings to this cooperation innovative approaches to problems involving the dynamics of dislocations in structures and the elasticity of structural materials. This is complemented by the French investigator's extensive experience in dislocation theory and numerical approaches to elasticity problems. The investigators are dealing with important issues in mechanics which are often stumbling blocks to effective evaluation of construction materials. Their joint effort will result in a unified theory and mathematical model which will advance our understanding of the mechanical behavior of structures and the effects of dislocation on fractured solids.

这个为期三年的奖项支持美国-法国在固体力学方面的合作研究，合作研究对象是圣地亚哥加利福尼亚大学的Xanthippi Markenscoff和巴黎大学材料科学研究所的Helmut Kirchner。他们的研究目的是建立一个数学模型来解决断裂力学中的位错效应。Markenscoff博士为这次合作带来了涉及结构中位错动力学和结构材料弹性问题的创新方法。这是由法国研究者在位错理论和弹性问题的数值方法的丰富经验补充。研究人员正在处理力学中的重要问题，这些问题往往是对建筑材料进行有效评估的绊脚石。他们的共同努力将产生统一的理论和数学模型，这将促进我们对结构的力学行为和位错对断裂固体的影响的理解。
