A Vickers indenter was loaded in dense HAP ceramics surface, and subcritical crack growth（SCG）behavior of Median/Radial cracks developed from the impression was measured. The fatigue parameter of the sintered HAP ceramics in 37℃ distilled water ranged from 12.5 to 19.0, and showed a good agreement with those measured by dynamic fatigue tests, though the fatigue parameter slightly showed a dependency of indentation loads. The relation between the stress intensity factor and the crack growth rate of the Median/Radial cracks was evaluated from the measured SCG behavior. As a results, it was found that the lower threshold stress intensity factor, KIth, of the sintered HAP ceramics in 37℃ distilled water existed within the range from 0.25KIC to 0.3KIC.","subitem_description_type":"Other"}]},"item_10002_full_name_75":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"4240","nameIdentifierScheme":"WEKO"}],"names":[{"name":"WAKAMATSU, NOBUKAZU"}]},{"nameIdentifiers":[{"nameIdentifier":"3788","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Doi, Yutaka"}]}]},"item_10002_radio_89":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_radio_item":"application/pdf"}]},"item_10002_relation_85":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"110008425137","subitem_relation_type_select":"NAID"}}]},"item_10002_source_id_84":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA10469472","subitem_source_identifier_type":"NCID"}]},"item_10002_textarea_76":{"attribute_name":"所属","attribute_value_mlt":[{"subitem_textarea_value":"朝日大学歯学部数学\nMathematics, Asahi University School of Dentistry\n"},{"subitem_textarea_value":"朝日大学歯学部口腔機能修復学講座歯科理工学分野\nDepartment of Dental Materials Science, Division of Oral Functional Science and Rehabilitation, Asahi University School of Dentistry"}]},"item_10002_version_type_95":{"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":"若松, 宣一"}],"nameIdentifiers":[{"nameIdentifier":"13793","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000000158594","nameIdentifierScheme":"CiNii ID","nameIdentifierURI":"http://ci.nii.ac.jp/nrid/1000000158594"},{"nameIdentifier":"00158594","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=00158594"}]},{"creatorNames":[{"creatorName":"土井, 豊"}],"nameIdentifiers":[{"nameIdentifier":"13794","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000040116067","nameIdentifierScheme":"CiNii ID","nameIdentifierURI":"http://ci.nii.ac.jp/nrid/1000040116067"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2014-01-22"}],"displaytype":"detail","filename":"ippan36_2942_2010.pdf","filesize":[{"value":"767.6 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"ippan36_2942_2010","url":"https://asahi-u.repo.nii.ac.jp/record/170/files/ippan36_2942_2010.pdf"},"version_id":"7b2fcc8f-d65b-4078-9bd4-b9ab3ec26feb"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"ハイドロキシアパタイト焼結体の37℃蒸留水中での疲労パラメータと下限界応力拡大係数","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ハイドロキシアパタイト焼結体の37℃蒸留水中での疲労パラメータと下限界応力拡大係数"},{"subitem_title":"Stress Corrosion Susceptibility Coefficient and Lower Threshold Stress Intensity Factor of Sintered Hydroxyapatite Ceramics in 37℃ Distilled Water","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"20","path":["58"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-01-22"},"publish_date":"2014-01-22","publish_status":"0","recid":"170","relation_version_is_last":true,"title":["ハイドロキシアパタイト焼結体の37℃蒸留水中での疲労パラメータと下限界応力拡大係数"],"weko_creator_id":"20","weko_shared_id":20},"updated":"2023-06-23T13:33:42.564582+00:00"}
