Title:<\/span> Probabilistic sizing of a fatigue crack on type 304 austenitic stainless steel from eddy current signals<\/p>\n\n\n\n Abstract:<\/span> This study attempted to probabilistically evaluate the size of a fatigue crack on a type 304 austenitic stainless flat plate from eddy current signals. Three fatigue cracks, whose depths ranged from 2 mm to 5 mm, were introduced into the plates using a four-point bending test. After the starter notches for the test were removed, eddy current testing was conducted using a differential-type pluspoint probe with a frequency of 200 kHz to gather signals due to cracks. The fatigue crack was modeled as a rectangular continuous domain with constant width and uniform electromagnetic properties inside. As mechanical damage transforms the austenitic phase into the martensitic phase, not only conductivity but also the permeability of the domain were explicitly considered. The depth and length of the cracks were evaluated using a Bayesian-based inverse algorithm assuming that the electromagnetic properties of a crack are either known (equal to air) or unknown. When a crack was modeled as air, the evaluated crack sizes deviated considerably from the actual sizes. By contrast, assuming the electromagnetic properties to be unknown provided better evaluations with their quantified uncertainty.<\/p>\n","protected":false},"excerpt":{"rendered":" \u7c73\u56fd\u6ede\u5728\u4e2d\u306eISEM2025\u6700\u7d42\u65e5\u306b\u3046\u308c\u3057\u3044\u77e5\u3089\u305b\u304c\u53c2\u308a\u307e\u3057\u305f\u3002\u7c73\u56fd\u975e\u7834\u58ca\u691c\u67fb\u5b66\u4f1a\u306e\u5b66\u4f1a\u8a8c\u3067\u3042\u308bMaterials Evaluation\u306b\u6295\u7a3f\u3057\u3066\u3044\u305f\u8ad6\u6587\u306e\u53d7\u7406 … <\/p>\n","protected":false},"author":1,"featured_media":5960,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[2,8],"tags":[151],"class_list":["post-14217","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-achievement","category-journal","tag-151"],"jetpack_featured_media_url":"https:\/\/i0.wp.com\/web.tohoku.ac.jp\/yusa\/wp-content\/uploads\/2020\/10\/shuku_vol2.jpg?fit=1200%2C1215","_links":{"self":[{"href":"http:\/\/web.tohoku.ac.jp\/yusa\/index.php\/wp-json\/wp\/v2\/posts\/14217","targetHints":{"allow":["GET"]}}],"collection":[{"href":"http:\/\/web.tohoku.ac.jp\/yusa\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/web.tohoku.ac.jp\/yusa\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/web.tohoku.ac.jp\/yusa\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"http:\/\/web.tohoku.ac.jp\/yusa\/index.php\/wp-json\/wp\/v2\/comments?post=14217"}],"version-history":[{"count":7,"href":"http:\/\/web.tohoku.ac.jp\/yusa\/index.php\/wp-json\/wp\/v2\/posts\/14217\/revisions"}],"predecessor-version":[{"id":14261,"href":"http:\/\/web.tohoku.ac.jp\/yusa\/index.php\/wp-json\/wp\/v2\/posts\/14217\/revisions\/14261"}],"wp:featuredmedia":[{"embeddable":true,"href":"http:\/\/web.tohoku.ac.jp\/yusa\/index.php\/wp-json\/wp\/v2\/media\/5960"}],"wp:attachment":[{"href":"http:\/\/web.tohoku.ac.jp\/yusa\/index.php\/wp-json\/wp\/v2\/media?parent=14217"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/web.tohoku.ac.jp\/yusa\/index.php\/wp-json\/wp\/v2\/categories?post=14217"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/web.tohoku.ac.jp\/yusa\/index.php\/wp-json\/wp\/v2\/tags?post=14217"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
