This award provides support for the participation of ten US scientists in a joint US-Japan seminar on "Micromechanics of Granular Materials". Granular material is an assembly of discrete particles, the macroscopic behavior of which is significantly influenced by the properties of those individual particles and their interactions. A wide range of engineering problems involve characterizing and handling granular materials, and solutions to these problems often rely on phenomenological formulas. To improve these phenomenological formulations, much research is undertaken aimed at increasing our understanding of how microscopic information relates to the macroscopic behavior of granular materials. Research undertaken by US and Japanese scientists in this area is complementary, US researchers concentrating on the formulation of rapidly deforming granular flows and the utilization of computer simulation, and Japanese researchers concentrating on the mathematical description and physical experiments of discrete systems. This seminar should therefore provide an excellent forum for scientists from each country to exchange results and discuss future research in this area. The seminar will be held on August 5-9, 1991 at Clarkson University, Postdam, New York. The co-organizers are Professor Hayley Shen, Department of Civil and Environmental Engineering, Clarkson University, and Professor Masao Satake, Department of Civil Engineering, Tohoku University, Japan. Specific topics to be discussed at the seminar include (1) constitutive relations with internal variables; (2) transiti- onal behavior including elastic to plastic, quasi-static and rapid deformation; and (3) two-phase flows. This will be the fourth seminar in a series that started in 1978. The prior seminars have been very valuable and the published proceedings well respected. This seminar will allow this successful cooperation between the two countries to continue, and should lead to further exchanges of information and more extensive research collaboration.

该奖项为10名美国科学家参加美日联合举办的“颗粒材料的微观力学”研讨会提供支持。颗粒材料是离散颗粒的集合，其宏观行为受单个颗粒的性质及其相互作用的影响很大。广泛的工程问题涉及颗粒材料的表征和处理，这些问题的解决方案通常依赖于唯象公式。为了改进这些现象学公式，进行了大量的研究，旨在增加我们对微观信息如何与颗粒材料的宏观行为相关的理解。美国和日本科学家在这一领域的研究是互补的，美国研究人员专注于快速变形颗粒流的公式和计算机模拟的利用，日本研究人员专注于离散系统的数学描述和物理实验。因此，这次研讨会应该为各国科学家交流成果和讨论这一领域的未来研究提供一个很好的论坛。研讨会将于1991年8月5日至9日在纽约波斯丹的克拉克森大学举行。联合主办方是克拉克森大学土木工程与环境工程系的Hayley沈教授和日本东北大学土木工程系的Masao Satake教授。研讨会将讨论的具体议题包括：(1)与内部变量的本构关系；(2)包括弹塑性、准静态和快速变形在内的跨边界行为；(3)两相流动。这将是1978年开始的一系列研讨会中的第四次。以前的研讨会非常有价值，发表的会议记录也很受尊重。这次研讨会将使两国之间的这种成功合作继续下去，并应导致进一步的信息交流和更广泛的研究合作。
