Tensie tests were conducted for four types of specimens of composite materials (unidirectional, 0度/90度 ply, boron fiber and shear lag test pieces), and for two types of specimens of 6061 aluminum alloy (tensile and shear test pieces). The results are summarized as follows : (1)Fiber breakage mainly relates to the AE wave characteristics in the low frequency range from 100 to 200 kHz. (2)Matrix damage and delamination mainly relates to the AE wave characteristics in the high frequency range from 400 kHz to 1 MHz. (3)The tensile and shear fracture of 6061 aluminum alloys relates to the AE wave characteristics in higher frequency ranges.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALTR1030000","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-1030","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":"0389-4010","subitem_source_identifier_type":"ISSN"}]},"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原動機部"},{"subitem_text_value":"航空宇宙技術研究所原動機部"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Aeroengine Division, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Aeroengine Division, National Aerospace Laboratory(NAL)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"祖父江, 靖"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"小河, 昭紀"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SOFUE, Yasushi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"OGAWA, Akinori","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":"2020-01-29"}],"displaytype":"detail","filename":"naltr01030.pdf","filesize":[{"value":"870.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltr01030.pdf","url":"https://jaxa.repo.nii.ac.jp/record/45289/files/naltr01030.pdf"},"version_id":"e9137445-425e-472d-a2bb-8072ce5d8d05"}]},"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":"AE法によるボロン繊維強化アルミニウム複合材料の破壊様式の研究(第2報)(AE波形とそのパワースペクトルからの検討)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"AE法によるボロン繊維強化アルミニウム複合材料の破壊様式の研究(第2報)(AE波形とそのパワースペクトルからの検討)"}]},"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":"45289","relation_version_is_last":true,"title":["AE法によるボロン繊維強化アルミニウム複合材料の破壊様式の研究(第2報)(AE波形とそのパワースペクトルからの検討)"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:41:59.164688+00:00"}
