0320968Abstract There has been a considerable effort in research at Oklahoma StateUniversity (OSU) in recent years in the fields of polymer fatigue, mechanics in themanufacturing of continuous thin materials, called webs, high-speed machining ofdifficult-to-machine materials, finishing of advanced ceramics, and fluid-structureinteractions. It has relied on extensive experimental investigations utilizing advancedinstrumentation. Technologies developed from these researches have been transferredto industry and have directly benefited sponsoring and other companies, such asEastman Kodak, 3M, Imation, Procter & Gamble, ALCOA, Rockwell Automation,Medtronic, and DuPont; and research findings have been published in leading archivaljournals and conferences. To continue research in these fields for the discovery inscience and engineering and for the development of new technologies transferable toindustry, a high-speed digital camera system is needed to investigate the high-speedmechanics accompanied with the research in these areas. The projects outlined in thisproposal require the ability to observe in situ high-speed phenomena occurring in thesefields. Experiments using the camera will be conducted to investigate the dynamic crackinitiation and propagation at high-speeds in both virgin and fatigue-damaged structuralpolymers for the purpose of identifying the onset and the mode of failure; to study high-speedmechanical slitting processes of plastic and metallic webs; to study themechanisms of high-speed machining processes of advanced materials; to study themechanisms of material removal in magnetic-field-assisted ceramic polishing processes;to study the interaction of thin films (solid) and turbulent air (fluid) in web manufacturingprocesses; to examine blade structural response and aerodynamic damping inturbomachine compressors; and to study the high-speed winding of webs.The availability of high-speed digital camera will greatly enhance theresearch infrastructure at OSU, as well as develop research infrastructure in Oklahoma,an EPSCoR state, to enhance research competitiveness of the state; it will also helpsupport productive research that will continuously benefit the U.S. industry, especiallythe web material industry through the Web Handling Research Center, the only centeron web handling in the world, that is sponsored by 17 U.S. companies.
