Description: This project supports a collaborative project by Drs. Arun Shukla of the Mechanical Engineering Department, University of Rhode Island (URI), and B.D. Agarwal, of the Mechanical Engineering Department, Indian Institute of Technology, Kanpur (IIT-K). The project aims at the study of damage initiation and growth, under dynamic loading conditions, in transparent birefringent composites made of glass fibers and polyester resin. An optical recording system of the Cranz Schardin type is to be designed and constructed at IIT-K. It will be capable of recording 20 pictures at rates from 20,000 to 900,000 frames per second. Specimens are to be photographed during the fracture process at very short time intervals. Initial fringe patterns are expected to give information on the the damage initiation conditions while subsequent fringe patterns will give information about the dynamic damage growth and damage arrest conditions. Scope: The topic of this research on fracture of composites under dynamic loads is timely since it is not currently well understood. The Indian and U.S. collaborators have expertise in dealing with the subject research. Their experiences complement each other well. This project represents a case of a potentially very useful international collaboration.

描述：该项目支持 Drs 的合作项目。 Arun Shukla，罗德岛大学机械工程系 (URI) 和 B.D. Agarwal，印度坎普尔理工学院 (IIT-K) 机械工程系教授。 该项目旨在研究由玻璃纤维和聚酯树脂制成的透明双折射复合材料在动态载荷条件下的损伤萌生和增长。 Cranz Schardin 类型的光学记录系统将由 IIT-K 设计和建造。 它将能够以每秒 20,000 至 900,000 帧的速度录制 20 张图片。 在断裂过程中以非常短的时间间隔对样品进行拍照。 初始条纹图案预计将提供有关损伤​​起始条件的信息，而后续条纹图案将提供有关动态损伤增长和损伤停止条件的信息。 范围：这项关于动态载荷下复合材料断裂的研究主题很及时，因为目前还没有得到很好的理解。 印度和美国的合作者拥有处理该主题研究的专业知识。 他们的经历相得益彰。 该项目代表了一个可能非常有用的国际合作案例。
