US-France Planning Visit: Study of Granular Material Crushing through Imaging and Discrete Element Modeling Simulation

在这次由国际科学与工程办公室欧洲和欧亚计划支持的计划访问中，Beena Sukumaran和Shreekanth Mandayam以及一名研究生将拜访法国梅茨的Paul Verlaine大学土木工程系的Ali Daouadji教授，对颗粒地质材料的粉碎进行联合实验、数值和理论研究。这项拟议的研究将涉及x射线计算机断层成像、离散元素建模和能够再现颗粒材料的应力-应变行为的理论模型的组合。这项计划中的多学科调查将涉及美国和法国的调查人员，他们拥有互补的专业知识。这项调查的技术影响可能会有利于岩土工程研究以及其他依赖于对颗粒力学的理解的领域。这项研究工作还将加强法国和美国科学家之间的科学合作，并在一项重要活动中为学生提供国际研究经验。罗文大学主要是一所本科院校，在STEM领域培训妇女和代表性不足的少数族裔方面取得了相当大的成功。

In this planning visit supported by the Europe and Eurasia Program of the Office of International Science and Engineering, Profs. Beena Sukumaran and Shreekanth Mandayam together with a graduate student will visit Prof. Ali Daouadji in the Civil Engineering Department at Université Paul Verlaine in Metz, France, to a joint experimental, numerical and theoretical study of the crushing of granular geologic materials. The proposed research will involve a combination of x-ray computed tomography imaging, discrete element modeling, and a theoretical model that can reproduce the stress-strain behavior of granular materials. This planned multidisciplinary investigation would involve US and French investigators with complementary expertise.The technical impact of this investigation is likely to benefit geotechnical engineering research as well as other fields that depend on an understanding of granular mechanics. The research effort would also enhance scientific collaboration between French and U.S. scientists and provide students with an international research experience in an important activity. Rowan University is a primarily undergraduate institution with considerable success in training women and underrepresented minorities in STEM fields.
