In particular, for the purpose of validation of the proposed method, probabilistic properties of microscopic representative sizes are identified by experimental observations from a set of actually fabricated specimens, and those are reflected to the analysis.From the comparison between the numerical and experimental results, the proposed method gives a good estimation of the probabilistic characteristics of the homogenized elastic properties, while the estimation error in the apparent strength estimation is larger. In order to improve the computational accuracy, it is pointed out that the random field modeling of microstructure should be carried out.","subitem_description_type":"Abstract"}]},"item_8_description_36":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究種目:基盤研究(C); 研究期間:2016~2020; 課題番号:16K05995; 研究分野:材料力学 計算力学 複合材料力学 最適設計; 科研費の分科・細目:","subitem_description_type":"Other"}]},"item_8_description_37":{"attribute_name":"資源タイプ(WEKO2)","attribute_value_mlt":[{"subitem_description":"Research Paper","subitem_description_type":"Other"}]},"item_8_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_8_publisher_14":{"attribute_name":"出版者 名前","attribute_value_mlt":[{"subitem_publisher":"近畿大学"}]},"item_8_text_10":{"attribute_name":"著者 役割","attribute_value_mlt":[{"subitem_text_value":"研究代表者"}]},"item_8_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Sakata, Sei-ichiro"}]},"item_8_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学理工学部; 教授"}]},"item_8_text_9":{"attribute_name":"著者所属(翻訳)","attribute_value_mlt":[{"subitem_text_value":"Kindai University"}]},"item_8_version_type_12":{"attribute_name":"版","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_be7fb7dd8ff6fe43","subitem_version_type":"NA"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"坂田, 誠一郎"},{"creatorName":"サカタ, セイイチロウ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{"nameIdentifierURI":""}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-11-08"}],"displaytype":"detail","filename":"16K05995seika.pdf","filesize":[{"value":"391.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"16K05995seika.pdf","url":"https://kindai.repo.nii.ac.jp/record/22103/files/16K05995seika.pdf"},"version_id":"9c0a2629-2ccd-4bca-9c6e-e6c35c02b70c"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"マルチスケール確率応力解析","subitem_subject_scheme":"Other"},{"subitem_subject":"三次元造形材料","subitem_subject_scheme":"Other"},{"subitem_subject":"複合材料","subitem_subject_scheme":"Other"},{"subitem_subject":"不均質材料","subitem_subject_scheme":"Other"},{"subitem_subject":"強度推定","subitem_subject_scheme":"Other"},{"subitem_subject":"信頼性評価","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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"マルチスケール確率応力解析を用いた不均質材料の新たな強度推定法の確立","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"マルチスケール確率応力解析を用いた不均質材料の新たな強度推定法の確立","subitem_title_language":"ja"},{"subitem_title":"Establishment of a novel method for strength estimation of heterogeneous materials by multiscale stochastic stress analysis","subitem_title_language":"en"}]},"item_type_id":"8","owner":"3","path":["4710"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2021-11-08"},"publish_date":"2021-11-08","publish_status":"0","recid":"22103","relation_version_is_last":true,"title":["マルチスケール確率応力解析を用いた不均質材料の新たな強度推定法の確立"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-31T06:51:03.985390+00:00"}
