Loading on specimens is interrupted at various displacement points, and fracture surfaces of the specimens are observed by scanning electron microscopy (SEM). Each method is effective in detecting the strict crack initiation at the middle of specimen thickness under static and dynamic loading conditions. J (mid) is proposed to define the fracture toughness of ductile cast iron. Crack tip opening displacement(CTOD) under the dynamic loading condition is smaller according to the results of calculation and SEM observation. It is considered that crack initiation under the dynamic loading condition is accelerated since the plastic deformation cannot follow up deflection of the specimen.","subitem_description_type":"Abstract"}]},"item_10001_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"・rights：日本機械学会\n・rights：本文データは学協会の許諾に基づきCiNiiから複製したものである\n・relation：isVersionOf：http://ci.nii.ac.jp/naid/110002371273/\n\n","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"一般社団法人日本機械学会"}]},"item_10001_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"CiNii"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/110002371273/","subitem_relation_type_select":"URI"}}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03875008","subitem_source_identifier_type":"ISSN"}]},"item_10001_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"山田, 伸弥"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"小林, 俊郎"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"YAMADA, Shinya","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KOBAYASHI, Toshiro","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":"2013-07-24"}],"displaytype":"detail","filename":"n03875008-0058-2088.pdf","filesize":[{"value":"477.9 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"n03875008-0058-2088","url":"https://repo.lib.tut.ac.jp/record/1247/files/n03875008-0058-2088.pdf"},"version_id":"870fe3ad-a0b4-41ee-bcba-3814a6e27560"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Fracture_Toughness","subitem_subject_scheme":"Other"},{"subitem_subject":"J-Integral","subitem_subject_scheme":"Other"},{"subitem_subject":"Crack_Opening_Displacement","subitem_subject_scheme":"Other"},{"subitem_subject":"Ductile_Cast_Iron","subitem_subject_scheme":"Other"},{"subitem_subject":"Dynamic_Fracture","subitem_subject_scheme":"Other"},{"subitem_subject":"Crack_Initiation","subitem_subject_scheme":"Other"},{"subitem_subject":"Fracture_Toughness","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"J-Integral","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Crack_Opening_Displacement","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Ductile_Cast_Iron","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Dynamic_Fracture","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Crack_Initiation","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"球状黒鉛鋳鉄における静的および動的破壊靱性の評価","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"球状黒鉛鋳鉄における静的および動的破壊靱性の評価"},{"subitem_title":"Static and Dynamic Fracture Toughness of Ductile Cast Iron","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"24","path":["9"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-07-24"},"publish_date":"2013-07-24","publish_status":"0","recid":"1247","relation_version_is_last":true,"title":["球状黒鉛鋳鉄における静的および動的破壊靱性の評価"],"weko_creator_id":"24","weko_shared_id":-1},"updated":"2023-06-19T07:54:43.578462+00:00"}
