The results obtained are summarized as follows. ( 1 ) Fatigue lives in laboratory air and Ringer's solution showed little difference. ( 2 )At high stress levels above 100 MPa, creep rupture time and fatigue failure time are nearly the same, but at low stress levels below 100 MPa, the latter is shorter than the former. This indicates that fatigue damage accumulation controls the fatigue fracture process at low stress levels. ( 3 ) During the fatigue process of bovine bone, several microcracks were initiated and propagated accompanied by crack coalescences among them. The crack path was zigzagged. ( 4 ) The relation-ship between the ratio of crack initiation cycles N_i to fatigue cycles N_f and stress amplitude was investigated. The ratio N_i/N_f decreased with a decrease of the stress amplitude region. ( 5 ) There is a linear relationship between crack growth rate da/dN and stress intensity factor ΔK on the log-log plot, and the Paris equation da/dN=CΔK^m holds, where C and m are C=5. 25×10^-9 and m=1. 49, respectively.","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":"10174","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000080109107","nameIdentifierScheme":"CiNii ID","nameIdentifierURI":"http://ci.nii.ac.jp/nrid/1000080109107"},{"nameIdentifier":"80109107","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://nrid.nii.ac.jp/nrid/1000080109107"}],"names":[{"name":"Goshima, Takahito"}]},{"nameIdentifiers":[{"nameIdentifier":"11189","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Nakamura, Yutaka"}]}]},"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":"五嶋, 孝仁"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"中村, 豊"}],"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A93-50.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"機械論文A93-50.pdf","url":"https://toyama.repo.nii.ac.jp/record/3237/files/機械論文A93-50.pdf"},"version_id":"53545ca5-a5e7-4775-8c24-377c9525dcd5"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Biomechanics","subitem_subject_scheme":"Other"},{"subitem_subject":"Bovine Bone","subitem_subject_scheme":"Other"},{"subitem_subject":"Fatigue","subitem_subject_scheme":"Other"},{"subitem_subject":"Crack Propagation","subitem_subject_scheme":"Other"},{"subitem_subject":"Crack Initiation","subitem_subject_scheme":"Other"},{"subitem_subject":"Stress Intensity","subitem_subject_scheme":"Other"},{"subitem_subject":"Factor Creep","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":"牛骨の疲労過程におけるき裂の発生と進展特性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"牛骨の疲労過程におけるき裂の発生と進展特性"}]},"item_type_id":"2","owner":"3","path":["558"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-01-17"},"publish_date":"2008-01-17","publish_status":"0","recid":"3237","relation_version_is_last":true,"title":["牛骨の疲労過程におけるき裂の発生と進展特性"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-25T12:42:14.758616+00:00"}
