We also developed a jig to be attached directly on the specimen for long-period measurement of internal deformation such as drying shrinkage and ASR. On the other hand, the internal volumetric strain is calculated from the displacement difference between the adjacent measurement positions calculated by the digital volume correlation. That volumetric strain had sufficient accuracy without the jig because the difference reduces the error. As the results, an X-ray CT image measurement method for measuring local shrinkage and expansion deformation inside the concrete specimen in the short-term and long-term was established.","subitem_description_type":"Abstract"}]},"item_8_description_36":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究種目：基盤研究(C);  研究期間：2017～2019;   課題番号：17K06522;   研究分野：コンクリート工学;   科研費の分科・細目：","subitem_description_type":"Other"}]},"item_8_description_37":{"attribute_name":"資源タイプ(WEKO2)","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_text_10":{"attribute_name":"著者 役割","attribute_value_mlt":[{"subitem_text_value":"研究代表者"},{"subitem_text_value":"研究分担者"},{"subitem_text_value":"研究分担者"}]},"item_8_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Fumoto, Takayuki"},{"subitem_text_language":"en","subitem_text_value":"Iwatsuki, Eiji"},{"subitem_text_language":"en","subitem_text_value":"Mikata, Yasuhiro"}]},"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"},{"subitem_text_value":"愛知工業大学工学部; 教授"},{"subitem_text_value":"大阪工業大学工学部; 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":"麓, 隆行"},{"creatorName":"フモト, タカユキ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3825","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"30315981","nameIdentifierScheme":"NRID","nameIdentifierURI":"https://nrid.nii.ac.jp/ja/search/?kw=30315981"}]},{"creatorNames":[{"creatorName":"岩月, 栄治"},{"creatorName":"イワツキ, エイジ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"43306","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"10278228","nameIdentifierScheme":"NRID","nameIdentifierURI":"https://nrid.nii.ac.jp/ja/search/?kw=10278228"}]},{"creatorNames":[{"creatorName":"三方, 康弘"},{"creatorName":"ミカタ, ヤスヒロ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"43307","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"60434784","nameIdentifierScheme":"NRID","nameIdentifierURI":"https://nrid.nii.ac.jp/ja/search/?kw=60434784"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-03-15"}],"displaytype":"detail","filename":"17K06522seika.pdf","filesize":[{"value":"433.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"17K06522seika.pdf","url":"https://kindai.repo.nii.ac.jp/record/21447/files/17K06522seika.pdf"},"version_id":"c404be60-0de7-44de-8ed8-775da344d11d"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"コンクリート","subitem_subject_scheme":"Other"},{"subitem_subject":"X線CT","subitem_subject_scheme":"Other"},{"subitem_subject":"画像相関法","subitem_subject_scheme":"Other"},{"subitem_subject":"体積ひずみ","subitem_subject_scheme":"Other"},{"subitem_subject":"圧縮応力","subitem_subject_scheme":"Other"},{"subitem_subject":"乾燥収縮","subitem_subject_scheme":"Other"},{"subitem_subject":"アルカリ骨材反応","subitem_subject_scheme":"Other"},{"subitem_subject":"凍結融解","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":"コンクリート内部の局所変形計測のためのX線CT画像計測法の開発","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"コンクリート内部の局所変形計測のためのX線CT画像計測法の開発","subitem_title_language":"ja"},{"subitem_title":"Development of X-ray CT image measurement method for local deformation in concrete","subitem_title_language":"en"}]},"item_type_id":"8","owner":"3","path":["4613"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2021-03-15"},"publish_date":"2021-03-15","publish_status":"0","recid":"21447","relation_version_is_last":true,"title":["コンクリート内部の局所変形計測のためのX線CT画像計測法の開発"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-09-13T05:23:41.009524+00:00"}
