U.S.-France Cooperative Research: Singularities in Mechanics

这项为期三年的奖项支持圣地亚哥加利福尼亚大学的Xanthippi Markenscoff和巴黎大学(南方)材料科学研究所的Helmut Kirchner在固体力学方面的美法合作研究。他们的研究目标是开发一种数学模型，解决断裂力学中的位错效应。Markenscoff博士为这一合作带来了创新的方法，以解决涉及结构中位错动力学和结构材料弹性的问题。此外，这位法国研究人员在位错理论和弹性问题的数值方法方面拥有丰富的经验。研究人员正在处理力学中的重要问题，这些问题往往是有效评估建筑材料的绊脚石。他们的共同努力将导致一个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破裂固体的影响的理解。

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.
