Especially, the impact response in the direction perpendicular to fibers is the most important, but tardy in research. In this report, first we treat wave reflection and transmission at the interface of different element materials, by using the one-dimensional theory of stress waves. Secondly, those results are applied to some simple models of unidirectional fiber-reinforced composite materials and impact responses in the direction perpendicular to fibers are calculated. Model I and II are composite structures in which two semi-infinite elastic solids are bonded with a thin layer made of a different material. Model III and IV are composed of two and three bonded layers, respectively. These models subjected to impact loading receive a larger tensile stress at the interface than those subjected to static loading, and it is predicted that the tensile fracture at the interface easily occurs.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0125656000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学宇宙航空研究所"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0563-8100","subitem_source_identifier_type":"ISSN"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00161914","subitem_source_identifier_type":"NCID"}]},"item_9_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学宇宙航空研究所"},{"subitem_text_value":"東京大学宇宙航空研究所"}]},"item_9_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Aeronautical Science, University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Aeronautical Science, University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"河田, 幸三"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"武田, 展雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KAWATA, Kozo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TAKEDA, Nobuo","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":"2020-01-24"}],"displaytype":"detail","filename":"SA0125656.pdf","filesize":[{"value":"391.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0125656.pdf","url":"https://jaxa.repo.nii.ac.jp/record/32419/files/SA0125656.pdf"},"version_id":"1d80e43a-785a-470e-b935-bb87bac5dfc5"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"<論文>一方向繊維強化材の繊維垂直方向衝撃応答について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"<論文>一方向繊維強化材の繊維垂直方向衝撃応答について"}]},"item_type_id":"9","owner":"1","path":["1890","1910"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"32419","relation_version_is_last":true,"title":["<論文>一方向繊維強化材の繊維垂直方向衝撃応答について"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:32:55.422571+00:00"}
