The stress intensity factor K_ρ at the initiation of crack extension detected by the DC potential method was related to the initial notch-tip radius ρ by K_ρ=K_0(1+ρ/ρ_0)^<1/2> where K_0 and ρ_0 are material constants. This was derived through the concept of the fictitious notch-tip radius proposed by Tanaka and Hirose. The values of material constants K_0 and ρ_0 took the lowest values for the material tempered at 300℃. The residual stress near the fracture surface measured by the X-ray diffraction technique was tension. The depth of the plastic zone ω_y was measured by the distribution of residual stress beneath the fracture surface. It was related to the stress intensity factor at crack initiation K_i by the following fracture mechanics equation : ω_y=α(K_i/σ_Y)^2 where σ_y is the yield stress and α is from 0.14 to 0.12. The values of residual stresses very close to the fracture surface tended to decrease with increasing K_i, and were found to be a single-valued function of the fracture strain at the notch-tip determined from K_0 and ρ_0 values based on the fictitious notch-tip radius concept.","subitem_description_type":"Abstract"}]},"item_4_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学大学院自然科学研究科","subitem_description_type":"Other"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本材料学会"}]},"item_4_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/110002300385/","subitem_relation_type_select":"URI"}}]},"item_4_rights_23":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"日本材料学会；本文データは日本材料学会の許諾に基づきCiNiiから複製したものである"}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AN00096175","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0514-5163","subitem_source_identifier_type":"ISSN"}]},"item_4_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":"矢島, 善次郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"広瀬, 幸雄"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"田中, 啓介"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"小河, 弘"}],"nameIdentifiers":[{}]}]},"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":"TE-PR-HIROSE-Y-783.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"TE-PR-HIROSE-Y-783.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/7918/files/TE-PR-HIROSE-Y-783.pdf"},"version_id":"43e14ff3-192c-49ed-9b54-22c4b3abf0a7"}]},"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":"高張力鋼の切欠きCT試験片の破壊じん性試験破面のX線的研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"高張力鋼の切欠きCT試験片の破壊じん性試験破面のX線的研究"},{"subitem_title":"X-Ray Diffraction Study on Fracture Surface Made by Fracture Toughness Tests of Blunt Notched CT Specimen of High Strength Steel","subitem_title_language":"en"}]},"item_type_id":"4","owner":"3","path":["936"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-03"},"publish_date":"2017-10-03","publish_status":"0","recid":"7918","relation_version_is_last":true,"title":["高張力鋼の切欠きCT試験片の破壊じん性試験破面のX線的研究"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-28T02:17:22.613432+00:00"}
