The distribution shape of fatigue life is found to be related to the shape of the S-(middle)N curve in the neighborhood of the test stress level. To compare the quantitative relationship between the scatter of fatigue life and the slope of the S-(middle)N curve in various test data, test stress levels were standardized by the median fatigue strength at 10(exp 5) cycles in each data, and standardized S-(middle)N curves, where “standardized”means the use of such standardized stress levels, were drawn. The standard deviation of log-life in either steels or aluminum alloys has an obvious linear relation on double logarithmic graph paper with the slope of the standardized S-(middle)N curve at the test stress level. The distribution of the median fatigue strength corresponding to each fatigue life obtained at one stress level is normal in shape and its standard deviation is nearly constant regardless of the test stress level in each data. On the basis of these results, a method for estimating fatigue life distribution is developed when the available information is limited either to a simple S-N curve only or to the original fatigue life data for the construction of such an S-N curve.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALTR0581000","subitem_description_type":"Other"}]},"item_3_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: NAL TR-581","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"航空宇宙技術研究所"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"National Aerospace Laboratory(NAL)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0389-4010","subitem_source_identifier_type":"ISSN"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"航空宇宙技術研究所機体第二部"},{"subitem_text_value":"航空宇宙技術研究所機体第二部"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Second Airframe Division, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Second Airframe Division, National Aerospace Laboratory(NAL)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"下河, 利行"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"浜口, 泰正"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SHIMOKAWA, Toshiyuki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"HAMAGUCHI, Yasumasa","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":"2020-01-29"}],"displaytype":"detail","filename":"naltr00581.pdf","filesize":[{"value":"746.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltr00581.pdf","url":"https://jaxa.repo.nii.ac.jp/record/44835/files/naltr00581.pdf"},"version_id":"2234f3e9-6d07-42e0-aad8-deadc24159b2"}]},"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":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"S-N曲線による疲労寿命分布推定","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"S-N曲線による疲労寿命分布推定"}]},"item_type_id":"3","owner":"1","path":["1893","1917"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"44835","relation_version_is_last":true,"title":["S-N曲線による疲労寿命分布推定"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:50:03.696915+00:00"}
