0422767 Arun Shukla描述：该奖项支持美国-印度合作研究，题为聚合物颗粒纳米复合材料的开发和表征。 这是一 深入研究聚合物颗粒纳米复合材料的加工及其两种不同聚合物体系（热固性树脂和热塑性塑料）的机械、断裂和多功能属性。合作研究将涉及罗得岛大学（URI）机械工程和应用力学系的Arun Shukla教授和印度理工学院坎普尔（IITK）机械工程系的P. Venkitnarayanan。 纳米复合材料的本构响应将在高应变速率下进行评估。动态条件下聚合物纳米复合材料中的静态和扩展裂纹的行为将使用超高速摄影和光学干涉测量法进行。在更精细的长度尺度的性能评估将尝试导致预测models.Scope的发展：在这两个机构的调查人员在处理和表征新型工程材料的专业知识，并在过去成功地合作下，美国国家科学基金会的联合计划与印度的科学技术部。该项目结合了复合材料专业人员的各种专业知识，并提供了在各自机构的专业设施。 这项研究将涉及两个机构的学生，技术人员和教职员工，并导致高级项目，技术论文，演示文稿和论文。 访问教师和学生将获得宝贵的接触材料合成的挑战和用于新材料的机械和断裂表征的各种实验技术。将通过各研究所的网站迅速传播和交流知识。

0422767Arun ShuklaDescription: This award supports the U.S.-India cooperative research entitled Development and Characterization of Polymer Particulate Nanocomposites. This is an in-depth investigation on the processing of polymer-particulate nanocomposites and their mechanical, fracture and multi-functional attributes for two different polymer systems, thermosetting resins and thermo plastics. The cooperative research will involve Professors Arun Shukla, Department of Mechanical Engineering and Applied Mechanics, University of Rhode Island (URI) and P. Venkitnarayanan, Department of Mechanical Engineering, Indian Institute of Technology Kanpur (IITK). The constitutive response of the nanocomposites will be evaluated at high strain rates. The behavior of stationary and propagating cracks in polymer nanocomposites under dynamic conditions will be performed using ultra-high speed photography and optical interferometry. Evaluation of properties at finer length scales will be attempted leading to the development of predictive models.Scope: The investigators at both institutions have expertise in processing and characterizing novel engineered materials and have successfully collaborated in the past under NSF's joint program with India's Department of Science & Technology. This project combines the diverse expertise of the PIs in composites and offers access to specialized facilities at the respective institutions. This research will involve students, technicians and faculty members at both institutions and result in senior projects, technical papers, presentations, and dissertations. Visiting faculty members and students will receive valuable exposure to the challenges of material synthesis and various experimental techniques used for mechanical and fracture characterization of novel materials. There will be quick dissemination and exchange of knowledge through the respective institutes websites.
