Using this function, we have started to try a development of stress-responsive self-strengthened metallic implants. Spinal fixation devices seem to be one of the applications for such the metals, and thus their responses to bending deformations were investigated in this study. As the results, the deformation-induced ω phase was observed in both the compression and tension sides of the bended rods. The metals with self-tunable elastic modulus exhibited high fatigue strengths under tension-tension modes so that high durability could be obtained by suitable surface strengthening treatments for suppressing fretting fatigue at the contacts between the components in spinal fixation devices during cyclic bending deformations.","subitem_description_type":"Abstract"}]},"item_8_description_36":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究種目:若手研究(A); 研究期間:2013~2016; 課題番号:25702027; 研究分野:材料工学; 科研費の分科・細目:","subitem_description_type":"Other"}]},"item_8_description_37":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Research Paper","subitem_description_type":"Other"}]},"item_8_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_8_publisher_14":{"attribute_name":"出版者 名前","attribute_value_mlt":[{"subitem_publisher":"近畿大学"}]},"item_8_relation_11":{"attribute_name":"著者 外部リンク","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-25702027/"}]}]},"item_8_text_10":{"attribute_name":"著者 役割","attribute_value_mlt":[{"subitem_text_value":"研究代表者"}]},"item_8_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"NAKAI, Masaaki"}]},"item_8_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学理工学部; 准教授"}]},"item_8_text_9":{"attribute_name":"著者所属(翻訳)","attribute_value_mlt":[{"subitem_text_value":"Kindai University"}]},"item_8_version_type_12":{"attribute_name":"版","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_be7fb7dd8ff6fe43","subitem_version_type":"NA"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"仲井, 正昭"},{"creatorName":"ナカイ, マサアキ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-11-01"}],"displaytype":"detail","filename":"25702027seika.pdf","filesize":[{"value":"1.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"25702027seika.pdf","url":"https://kindai.repo.nii.ac.jp/record/18816/files/25702027seika.pdf"},"version_id":"0615a337-c796-4f0b-b700-9fd963e5a642"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"生体材料","subitem_subject_scheme":"Other"},{"subitem_subject":"チタン合金","subitem_subject_scheme":"Other"},{"subitem_subject":"変形誘起相変態","subitem_subject_scheme":"Other"},{"subitem_subject":"オメガ相","subitem_subject_scheme":"Other"},{"subitem_subject":"疲労特性","subitem_subject_scheme":"Other"},{"subitem_subject":"脊椎固定","subitem_subject_scheme":"Other"},{"subitem_subject":"曲げ変形","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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"骨の特異力学機能に学ぶ応力応答性自己強化金属製インプラントの開発原理","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"骨の特異力学機能に学ぶ応力応答性自己強化金属製インプラントの開発原理"},{"subitem_title":"Principle for development of stress-responsive self-strengthened metallic implants on the basis of unique mechanical function of bone","subitem_title_language":"en"}]},"item_type_id":"8","owner":"3","path":["4374"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-11-01"},"publish_date":"2017-11-01","publish_status":"0","recid":"18816","relation_version_is_last":true,"title":["骨の特異力学機能に学ぶ応力応答性自己強化金属製インプラントの開発原理"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-06-20T21:49:03.051097+00:00"}
