The angle section and the T-section stiffeners were tested at room temperature and at 300 C. For the angle section stiffeners, the drop in the buckling strength at 300 C was less than five percent compared with the room temperature test results when the aspect ratio is greater than four, and the drop in the final failure strength was less than 15 percent. The predicted buckling strengths of the specimen with the mechanical fixture were close to the test results. For the T-section stiffeners, the primary objective of this study was to evaluate the effect of the corner radius at a flange-web junction on buckling and on final failure strength. The buckling strengths predicted with the analytical model including an actual corner shape coincide with the experimental test results, and a significant increase in buckling strength due to the increase in the corner radius was shown.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0000445000","subitem_description_type":"Other"}]},"item_3_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: NAL TR-1286","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"航空宇宙技術研究所"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"National Aerospace Laboratory (NAL)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1347-4588","subitem_source_identifier_type":"ISSN"}]},"item_3_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00311347","subitem_source_identifier_type":"NCID"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"航空宇宙技術研究所 構造力学部"},{"subitem_text_value":"航空宇宙技術研究所 機体部"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"National Aerospace Laboratory Structural Mechanics Division"},{"subitem_text_language":"en","subitem_text_value":"National Aerospace Laboratory Airframe Division"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"三本木, 茂夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"濱口, 泰正"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sanbongi, Shigeo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hamaguchi, Yasumasa","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-27"}],"displaytype":"detail","filename":"naltr01286.pdf","filesize":[{"value":"1.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltr01286.pdf","url":"https://jaxa.repo.nii.ac.jp/record/39762/files/naltr01286.pdf"},"version_id":"bc569156-e8f7-4ae7-ad5d-2548df91a101"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"補強部材","subitem_subject_scheme":"Other"},{"subitem_subject":"積層複合材料","subitem_subject_scheme":"Other"},{"subitem_subject":"カーボン/ポリイミド複合材","subitem_subject_scheme":"Other"},{"subitem_subject":"座屈特性","subitem_subject_scheme":"Other"},{"subitem_subject":"最終破壊特性","subitem_subject_scheme":"Other"},{"subitem_subject":"宇宙往還機構造材","subitem_subject_scheme":"Other"},{"subitem_subject":"固定金具","subitem_subject_scheme":"Other"},{"subitem_subject":"コーナー半径","subitem_subject_scheme":"Other"},{"subitem_subject":"フランジ","subitem_subject_scheme":"Other"},{"subitem_subject":"ウェブ","subitem_subject_scheme":"Other"},{"subitem_subject":"stiffener","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"laminated composites","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"carbon polyimide composites","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"buckling characteristics","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"final failure characteristics","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"spaceplane structure","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"mechanical fixture","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"corner radius","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"flange","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"web","subitem_subject_language":"en","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":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"カーボン/ポリイミド複合材スティフナの圧縮座屈強度","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"カーボン/ポリイミド複合材スティフナの圧縮座屈強度"}]},"item_type_id":"3","owner":"1","path":["1893","1917"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"39762","relation_version_is_last":true,"title":["カーボン/ポリイミド複合材スティフナの圧縮座屈強度"],"weko_creator_id":"1","weko_shared_id":1},"updated":"2023-06-20T19:19:24.938995+00:00"}
