In this study, the authors investigated on the behavior of surface crack propagation using three TMCP steels with different SImax, and proposed the method of crack propagation analysis considering the effect of micro-separations. The results may be summarized as follows: (1) As SImax increase, propagation pattern of surface crack become shallow. (2) The macroscopic fatigue crack propagation can be analyzed with the assumption that the fatigue crack propagation in the direction of plate thickness passes through between estimated microseparations. (3) This estimation method shows the good agreement with the experimental change of aspect ratio for surface crack.","subitem_description_type":"Abstract"}]},"item_3_description_64":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"長崎大学工学部研究報告, 21(37), pp.157-166; 1991","subitem_description_type":"Other"}]},"item_3_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"長崎大学工学部"}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00178418","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"02860902","subitem_source_identifier_type":"ISSN"}]},"item_3_source_id_8":{"attribute_name":"EISSN","attribute_value_mlt":[{"subitem_source_identifier":"18805574","subitem_source_identifier_type":"ISSN"}]},"item_3_text_63":{"attribute_name":"出版者別言語","attribute_value_mlt":[{"subitem_text_value":"Faculty of Engineering, Nagasaki University"}]},"item_3_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Junichi, Katsuta"}],"nameIdentifiers":[{"nameIdentifier":"52356","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kawano, Kazuyoshi"}],"nameIdentifiers":[{"nameIdentifier":"52357","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sakai, Kouji"}],"nameIdentifiers":[{"nameIdentifier":"52358","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakajima, Masaki"}],"nameIdentifiers":[{"nameIdentifier":"52359","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-22"}],"displaytype":"detail","filename":"kogaku21_37_09.pdf","filesize":[{"value":"1.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"kogaku21_37_09.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/14371/files/kogaku21_37_09.pdf"},"version_id":"dac8ccbc-8f9c-46d3-a957-c63449d313d5"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Analysis of Surface Crack Propagation Considering the Effect of Micro-separations","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Analysis of Surface Crack Propagation Considering the Effect of Micro-separations"}]},"item_type_id":"3","owner":"2","path":["1205"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-10-25"},"publish_date":"2010-10-25","publish_status":"0","recid":"14371","relation_version_is_last":true,"title":["Analysis of Surface Crack Propagation Considering the Effect of Micro-separations"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-16T00:20:15.439054+00:00"}
