Two methods, developed by Morishita and Ono in the field of mathematical ecology, were used in analyzing the spatial distributions of Cracks. The following results were obtained. The spatial distributions of cracks are influenced by both stress amplitude and stress cycling. In the high stress amplitude region, the distributions are nearly random, while in the low stress amplitude region, the distributions have clumps indicating nonrandom distribution. This result was common to both fatigue in air and corrosion fatigue. With increasing stress cycling, the spatial distributions of cracks approach random distributions in the high stress amplitude region, while in the low stress amplitude region, the distributions show a strong tendency to have two kinds of clumps whose sizes are 1/4 mm^2 and 8 mm^2.","subitem_description_type":"Abstract"}]},"item_2_description_40":{"attribute_name":"資源タイプ(DSpace)","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_2_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"10173","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"9000002438640","nameIdentifierScheme":"CiNii ID","nameIdentifierURI":"http://ci.nii.ac.jp/nrid/9000002438640"},{"nameIdentifier":"60019221","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://nrid.nii.ac.jp/nrid/1000060019221"}],"names":[{"name":"Ishihara, Sotomi"}]},{"nameIdentifiers":[{"nameIdentifier":"10202","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000090019216","nameIdentifierScheme":"CiNii ID","nameIdentifierURI":"http://ci.nii.ac.jp/nrid/1000090019216"},{"nameIdentifier":"90019216","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://nrid.nii.ac.jp/nrid/1000090019216"}],"names":[{"name":"Shiozawa, Kazuaki"}]},{"nameIdentifiers":[{"nameIdentifier":"11263","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"9000002438641","nameIdentifierScheme":"CiNii ID","nameIdentifierURI":"http://ci.nii.ac.jp/nrid/9000002438641"}],"names":[{"name":"Miyao, Kazyu"}]},{"nameIdentifiers":[{"nameIdentifier":"11468","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kamishima, Yuuji"}]}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"社団法人日本機械学会"}]},"item_2_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"rights: 本文データは社団法人日本機械学会の許諾に基づきCiNiiから複製したものである"}]},"item_2_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN0018742X","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03875008","subitem_source_identifier_type":"ISSN"}]},"item_2_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":"石原, 外美"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"塩澤, 和章"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"宮尾, 嘉寿"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"神島, 裕児"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-16"}],"displaytype":"detail","filename":"機械論文A90-494.pdf","filesize":[{"value":"524.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"機械論文A90-494.pdf","url":"https://toyama.repo.nii.ac.jp/record/3281/files/機械論文A90-494.pdf"},"version_id":"6e437250-f4f6-4462-809c-16e9e686aa67"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Fatigue","subitem_subject_scheme":"Other"},{"subitem_subject":"Corrosion Fatigue","subitem_subject_scheme":"Other"},{"subitem_subject":"Statistical Treatment","subitem_subject_scheme":"Other"},{"subitem_subject":"Spatial Distribution","subitem_subject_scheme":"Other"},{"subitem_subject":"Carbon Steel","subitem_subject_scheme":"Other"},{"subitem_subject":"Stress Amplitude","subitem_subject_scheme":"Other"},{"subitem_subject":"Stress Cycling","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"炭素鋼平滑試験片の平面曲げ疲労過程における複数き裂の空間分布 : 応力振幅および繰返し数依存性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"炭素鋼平滑試験片の平面曲げ疲労過程における複数き裂の空間分布 : 応力振幅および繰返し数依存性"}]},"item_type_id":"2","owner":"3","path":["558"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-01-18"},"publish_date":"2008-01-18","publish_status":"0","recid":"3281","relation_version_is_last":true,"title":["炭素鋼平滑試験片の平面曲げ疲労過程における複数き裂の空間分布 : 応力振幅および繰返し数依存性"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-25T12:40:46.784187+00:00"}
