But it seems that the effect of the plastic preworking on the fatigue strength and the propagative behavior of the fatigue crack are hardly studied under con­sideration of mutual relations. \n   Therefore, in this paper, for the plastic torsional preworked circumferentially notched bar of S17C (JIS G 4051), the prework dependence of the fatigue strength under rotary bending tests was studied and that of the propagative behavior of the fatigue crack was discussed by means of the result of Liu's dimensional analysis and stress intensity factor. \nThe following conclusions can be drawn :\n(1)\tThe suitable plastic torsional prework is effective in increasing the fatigue limit of the smooth and notched specimens, but the excessive preworking tends to decrease it. And the smooth specimen is more effective than notched one in increasing the fatigue limit.\n(2)\tThe index number of stress intensity factor is from 2.48 to 0.98, and decreases in according to the rate of preworking.\n(3)\tThe occurence of the fatigue crack is most delayed and the crack propagation speed is the slowest for the notched specimen which is preworked at the nearly most suitable degree in increasing the fatigue limit.","subitem_description_type":"Abstract"}]},"item_7_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00011728","subitem_identifier_reg_type":"JaLC"}]},"item_7_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"金沢大学工学部 = Faculty of Technology Kanazawa University"}]},"item_7_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AN00044309","subitem_source_identifier_type":"NCID"}]},"item_7_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0022-832X","subitem_source_identifier_type":"ISSN"}]},"item_7_version_type_25":{"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":"柴原, 正雄"}],"nameIdentifiers":[{"nameIdentifier":"11635","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"宮崎, 肇"}],"nameIdentifiers":[{"nameIdentifier":"18340","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":"2017-10-03"}],"displaytype":"detail","filename":"AN00044309-11-2-67.pdf","filesize":[{"value":"220.6 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"AN00044309-11-2-67.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/11741/files/AN00044309-11-2-67.pdf"},"version_id":"a83ef124-123d-428d-b812-cac50e03a21e"}]},"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":"低炭素鋼切欠き材における疲労強度と疲れき裂進展のねじり予加工依存性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"低炭素鋼切欠き材における疲労強度と疲れき裂進展のねじり予加工依存性"},{"subitem_title":"The Plastic Torsional Prework Dependence of the Fatigue Strength and Crack Propagation for Notched Low Carbon Steel Bars","subitem_title_language":"en"}]},"item_type_id":"7","owner":"3","path":["1030"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-03"},"publish_date":"2017-10-03","publish_status":"0","recid":"11741","relation_version_is_last":true,"title":["低炭素鋼切欠き材における疲労強度と疲れき裂進展のねじり予加工依存性"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-27T09:07:05.721083+00:00"}
