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.

在这次由国际科学与工程办公室欧洲和欧亚计划支持的规划访问中，教授。Beena Sukharan和Shreekanth Mandayam以及一名研究生将访问法国梅斯Paul Verlaine大学土木工程系的Ali Daouadji教授，对粒状地质材料的破碎进行联合实验、数值和理论研究。 拟议的研究将涉及x射线计算机断层扫描成像，离散元建模和理论模型，可以重现粒状材料的应力-应变行为的组合。 这项计划中的多学科调查将涉及美国和法国的调查人员，他们具有互补的专业知识。这项调查的技术影响可能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。 研究工作还将加强法国和美国科学家之间的科学合作，并为学生提供一个重要活动的国际研究经验。 罗文大学是一所主要的本科院校，在STEM领域培训女性和代表性不足的少数民族方面取得了相当大的成功。
