翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Electrochemical fatigue crack sensor ： ウィキペディア英語版 Electrochemical fatigue crack sensor An Electrochemical Fatigue Crack Sensor (EFCS) is a type of low cost electrochemical nondestructive dynamic testing method used primarily in the aerospace and transportation infrastructure industries. The method is used to locate surface-breaking and slightly subsurface defects in all metallic materials.〔(【引用サイトリンク】url=http://www.arema.org/files/library/2009_Conference_Proceedings/Inspection_of_Fatigue_Cracks_on_a_CN_Bridge_Using_The_Electrochemical_Fatigue_Sensos.pdf )〕 In bridge structures, EFCS is used at known fatigue susceptible areas, such as sharp-angled coped beams, stringer to beam attachments, and the toe of welds. This dynamic testing can be a form of short term or long term monitoring, as long as the structure is undergoing dynamic cyclic loading. ==History== The Electrochemical Fatigue Sensor (EFS) is the only Electrochemical Fatigue Crack Sensors (EFCS) on the market. Its history is below: In 1992, Dr. Campbell Laird and Dr. Yuanfeng Li invented the EFS™. The EFS™ relies on a patented electrical test 〔(Patents # 6,026,691 )〕〔(Patents # 7,572,360 )〕 method, which monitors the current flow at the surface of a metal while it is being mechanically flexed. The output current resembles a heart’s EKG pattern and can be interpreted to indicate the degree of fatigue as well as the presence of cracks in their earliest stages of development. The technology behind EFS was devised by researchers from the U.S. Air Force and the University of Pennsylvania for use in the aerospace industry. The original research was aimed at developing a technology for detecting problem cracks in airframes and engines. Since that time, additional research and development has resulted in the adaptation of the EFS system for steel bridge inspection. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Electrochemical fatigue crack sensor」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
