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.

[0422767]该奖项支持美印合作研究项目“聚合物颗粒纳米复合材料的开发和表征”。本文对热固性树脂和热塑性塑料两种不同聚合物体系的聚合物颗粒纳米复合材料及其力学、断裂和多功能特性进行了深入研究。合作研究将涉及罗德岛大学机械工程与应用力学系的Arun Shukla教授和印度坎普尔理工学院机械工程系的P. Venkitnarayanan教授。研究了高应变速率下纳米复合材料的本构响应。采用超高速摄影和光学干涉测量技术，研究了动态条件下聚合物纳米复合材料中固定裂纹和扩展裂纹的行为。将尝试在更细的长度尺度上评估属性，从而开发预测模型。研究范围：两家机构的研究人员在处理和表征新型工程材料方面具有专业知识，并且在过去的国家科学基金会与印度科技部的联合项目中成功合作。该项目结合了pi在复合材料领域的各种专业知识，并提供了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，并产生高级项目、技术论文、演讲和学位论文。访问教师和学生将有机会接触到材料合成的挑战，以及用于新材料的机械和断裂表征的各种实验技术。我们会透过各研究所的网站，迅速传播和交流知识。
