A tensile and a low cycle fatigue test (strain-controlled) were conducted with plate and round bar specimens made of the niobium alloy. The tests were conducted in air at a room temperature and stress-strain curves were obtained in each cycle. Obtained data from the tests were used to determine the material parameters employed in the constitutive equation. Stress-strain curves and damage-evolution curves were also simulated and the validity of material parameters was confirmed by comparing calculated values with test results. Fatigue life analysis was also conducted and the results were compared with the experimental values. From the results, it is expected that the developed constitutive equations and determined material parameters can be used effectively to predict the mechanical features and the life of low cycle fatigue for the niobium alloy.","subitem_description_type":"Other"}]},"item_7_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: 図版あり","subitem_description_type":"Other"}]},"item_7_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains illustrations","subitem_description_type":"Other"}]},"item_7_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: DS1540301008","subitem_description_type":"Other"}]},"item_7_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Japan Society for Aeronautical and Space Sciences"}]},"item_7_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"日本航空宇宙学会"}]},"item_7_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1344-6460","subitem_source_identifier_type":"ISSN"}]},"item_7_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11307372","subitem_source_identifier_type":"NCID"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"升岡, 正"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"都井, 裕"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"長田, 泰一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"香河, 英史"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"池田, 博英"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Masuoka, Tadashi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Toi, Yutaka","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nagata, Taiichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kagawa, Hideshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ikeda, Hirohide","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Damage Mechanics","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Niobium Alloy","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Low Cycle Fatigue","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":"損傷力学に基づくニオブ合金材の疲労寿命予測","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"損傷力学に基づくニオブ合金材の疲労寿命予測"}]},"item_type_id":"7","owner":"1","path":["1888"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-02-01"},"publish_date":"2016-02-01","publish_status":"0","recid":"21657","relation_version_is_last":true,"title":["損傷力学に基づくニオブ合金材の疲労寿命予測"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T03:32:11.390993+00:00"}
