Clothiaux, John D.2014-03-142014-03-141990-05-15etd-11072008-063531http://hdl.handle.net/10919/45476The suitability of using rain-flow reconstructions as an alternative to an original loading spectrum for component fatigue life testing is investigated. A modified helicopter maneuver history is used for the rain-flow cycle counting and history regenerations. Experimental testing on a notched test specimen over a wide range of loads produces similar lives for the original history and the reconstructions. The test lives also agree with a simplified local strain analysis performed on the specimen utilizing the rain-flow cycle count. The rain-flow reconstruction technique is shown to be a viable test spectrum alternative to storing the complete original load history, especially in saving computer storage space and processing time. A description of the regeneration method, the simplified life prediction analysis, and the experimental methods are included in the investigation.vii, 101 leavesBTDapplication/pdfenIn CopyrightLD5655.V855 1990.C568Rainfall intensity duration frequencies -- ResearchThesishttp://scholar.lib.vt.edu/theses/available/etd-11072008-063531/
