As a result, it was clarified that these two factors have little effect on the stress relaxation behavior and draw a master curve of shear relaxation modulus with almost the same shape in any glass. In addition, we tried to measure the viscosity by the parallel plate test and succeeded in calculating the shift factor from the estimated viscosity. In other words, it has become possible to significantly reduce the measurement time for the shift factor compared to the conventional creep test. Furthermore, the parallel plate tests with an extremely low loads using a thermomechanical analyzer were also performed, and it was clarified that the shift factors are not affected by the measured loads.","subitem_description_type":"Abstract"}]},"item_8_description_36":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究種目：基礎研究(C);  研究期間：2018～2020;   課題番号：18K03856;   研究分野：材料力学;   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_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":"ITO, Hiroaki"}]},"item_8_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学工学部; 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":"伊藤, 寛明"},{"creatorName":"イトウ, ヒロアキ","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":"2022-03-07"}],"displaytype":"detail","filename":"18K03856seika.pdf","filesize":[{"value":"798.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"18K03856seika.pdf","url":"https://kindai.repo.nii.ac.jp/record/22390/files/18K03856seika.pdf"},"version_id":"9b9e1775-74e0-4235-8550-635670f80a12"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"熱粘弾性特性","subitem_subject_scheme":"Other"},{"subitem_subject":"応力緩和","subitem_subject_scheme":"Other"},{"subitem_subject":"シフトファクタ","subitem_subject_scheme":"Other"},{"subitem_subject":"粘度測定","subitem_subject_scheme":"Other"},{"subitem_subject":"ネットワーク構造","subitem_subject_scheme":"Other"},{"subitem_subject":"光学ガラス","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":"粘度測定によるガラスの熱粘弾性特性評価技術の確立","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"粘度測定によるガラスの熱粘弾性特性評価技術の確立"},{"subitem_title":"Establishment of evaluation technique for thermo-viscoelastic property of glass using viscosity measurement","subitem_title_language":"en"}]},"item_type_id":"8","owner":"3","path":["4710"],"pubdate":{"attribute_name":"公開日","attribute_value":"2022-03-07"},"publish_date":"2022-03-07","publish_status":"0","recid":"22390","relation_version_is_last":true,"title":["粘度測定によるガラスの熱粘弾性特性評価技術の確立"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-20T19:46:43.974890+00:00"}
