Abstract

0320968 Abstract There has been a considerable effort in research at Oklahoma State University (OSU) in recent years in the fields of polymer fatigue, mechanics in the manufacturing of continuous thin materials, called webs, high-speed machining of difficult-to-machine materials, finishing of advanced ceramics, and fluid-structure interactions. It has relied on extensive experimental investigations utilizing advanced instrumentation. Technologies developed from these researches have been transferred to industry and have directly benefited sponsoring and other companies, such as Eastman Kodak, 3M, Imation, Procter & Gamble, ALCOA, Rockwell Automation, Medtronic, and DuPont; and research findings have been published in leading archival journals and conferences. To continue research in these fields for the discovery in science and engineering and for the development of new technologies transferable to industry, a high-speed digital camera system is needed to investigate the high-speed mechanics accompanied with the research in these areas. The projects outlined in this proposal require the ability to observe in situ high-speed phenomena occurring in these fields. Experiments using the camera will be conducted to investigate the dynamic crack initiation and propagation at high-speeds in both virgin and fatigue-damaged structural polymers for the purpose of identifying the onset and the mode of failure; to study high-speed mechanical slitting processes of plastic and metallic webs; to study the mechanisms of high-speed machining processes of advanced materials; to study the mechanisms of material removal in magnetic-field-assisted ceramic polishing processes; to study the interaction of thin films (solid) and turbulent air (fluid) in web manufacturing processes; to examine blade structural response and aerodynamic damping in turbomachine compressors; and to study the high-speed winding of webs. The availability of high-speed digital camera will greatly enhance the research infrastructure at OSU, as well as develop research infrastructure in Oklahoma, an EPSCoR state, to enhance research competitiveness of the state; it will also help support productive research that will continuously benefit the U.S. industry, especially the web material industry through the Web Handling Research Center, the only center on web handling in the world, that is sponsored by 17 U.S. companies.
