Don), Agathis (Agathis sp.), Buna (Fagus crenata Bl.), and Katsura (Cercidiphyllum japonicum Sieb. and Zucc.). The specimens were cut with the grain angles of 0 to 90 degrees at the interval of 15 degrees between the grain direction and long axis, and uniaxial compression tests were made. The relationships between the compressive strengths and the grain angles were represented by the Hankinson's formula and the formula modified by introducing the strength in the direction of 45 degrees with respect to the grain. The Hankinson's formula gave a proper prediction for the relationships between the compressive strengths and the grain angles except for Agathis which was located at the lower position than the testing data. On the contrary, the modified equation yielded a good relationship for all data.","subitem_description_type":"Abstract"},{"subitem_description":"繊維傾斜角と強度の関係を与えるHankinsonの式を，様々な木材の単軸圧縮試験によって検討した。また，繊維方向と45°傾いた方向の強度をHankinsonの式に導入することによって改造した。45°傾いた方向の強度が大きい場合，Hankinsonの式では全体の繊維傾斜角と強度の関係を的確に表現することができなかった。これに対して，改造した式は全体の繊維傾斜角と強度の関係を的確に表現することができた。","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"54736","nameIdentifierScheme":"WEKO"}],"names":[{"name":"吉原, 浩"}]},{"nameIdentifiers":[{"nameIdentifier":"54737","nameIdentifierScheme":"WEKO"}],"names":[{"name":"天野, 慎太郎"}]},{"nameIdentifiers":[{"nameIdentifier":"54738","nameIdentifierScheme":"WEKO"}],"names":[{"name":"太田, 正光"}]}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学大学院農学生命科学研究科附属演習林"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00162451","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03716007","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"610","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"The Tokyo University Forests"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学農学部林産学科"},{"subitem_text_value":"電気通信大学"},{"subitem_text_value":"Department of Forest Products, Faculty of Agriculture, The University of Tokyo"},{"subitem_text_value":"University of Electro Communications"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"YOSHIHARA, Hiroshi"}],"nameIdentifiers":[{"nameIdentifier":"54733","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"AMANO, Shintaro"}],"nameIdentifiers":[{"nameIdentifier":"54734","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"OHTA, Masamitsu"}],"nameIdentifiers":[{"nameIdentifier":"54735","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-06-09"}],"displaytype":"detail","filename":"esrh093001.pdf","filesize":[{"value":"306.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"esrh093001.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25441/files/esrh093001.pdf"},"version_id":"5dddfa18-25d8-45e8-b550-15dd498412fb"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Hankinson's formula","subitem_subject_scheme":"Other"},{"subitem_subject":"Grain orientation","subitem_subject_scheme":"Other"},{"subitem_subject":"Uniaxial-compression test","subitem_subject_scheme":"Other"},{"subitem_subject":"Uniaxial strength","subitem_subject_scheme":"Other"},{"subitem_subject":"Hankinsonの式","subitem_subject_scheme":"Other"},{"subitem_subject":"繊維傾斜角","subitem_subject_scheme":"Other"},{"subitem_subject":"単軸圧縮試験","subitem_subject_scheme":"Other"},{"subitem_subject":"圧縮強さ","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Relationship between the Strength and Grain Orientation of Wood : Examination and modification of the Hankinson's Formula","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Relationship between the Strength and Grain Orientation of Wood : Examination and modification of the Hankinson's Formula"}]},"item_type_id":"4","owner":"1","path":["2556","2555"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-09-03"},"publish_date":"2014-09-03","publish_status":"0","recid":"25441","relation_version_is_last":true,"title":["Relationship between the Strength and Grain Orientation of Wood : Examination and modification of the Hankinson's Formula"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:03:41.109318+00:00"}
