As microscopic random variables, volume fraction, shape and location of holes in the material are taken into account.At first, influence of the microscopic random variations on the homogenized properties and the stresses is analysed with the multiscale finite element method and the Monte-Carlo simulation, and the results show necessity of the multiscale stochastic stress analysis for a reliability-based design of the material. In particular, mportance of considering the non-uniformity of the microscopic random variation is indicated. The numerical results on the stochastic homogenization analysis with the perturbation-based method are compared with the results of the Monte-Carlo simulation and experiments, and validity and effectiveness of the approach are shown.","subitem_description_type":"Abstract"}]},"item_8_description_36":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究種目：若手研究(B);  研究期間：2011～2014;   課題番号：23760097;   研究分野：材料力学, 計算力学;   科研費の分科・細目：","subitem_description_type":"Other"}]},"item_8_description_37":{"attribute_name":"資源タイプ","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_relation_11":{"attribute_name":"著者 外部リンク","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/d/r/80325042.ja.html"}]}]},"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; 准教授"}]},"item_8_text_9":{"attribute_name":"著者所属(翻訳)","attribute_value_mlt":[{"subitem_text_value":"Kinki University"}]},"item_8_version_type_12":{"attribute_name":"版","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":"坂田,  誠一郎"},{"creatorName":"サカタ, セイイチロウ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-17"}],"displaytype":"detail","filename":"23760097seika.pdf","filesize":[{"value":"264.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"23760097seika.pdf","url":"https://kindai.repo.nii.ac.jp/record/3488/files/23760097seika.pdf"},"version_id":"d71e1a69-8402-4d62-8261-b9bfa6748e0f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"確率均質化解析","subitem_subject_scheme":"Other"},{"subitem_subject":"マルチスケール確率応力解析","subitem_subject_scheme":"Other"},{"subitem_subject":"多孔質材料","subitem_subject_scheme":"Other"},{"subitem_subject":"信頼性設計","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":"多孔質材料のマルチスケール確率応力解析および信頼性設計法に関する研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"多孔質材料のマルチスケール確率応力解析および信頼性設計法に関する研究"}]},"item_type_id":"8","owner":"3","path":["2987","2988"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-11-18"},"publish_date":"2015-11-18","publish_status":"0","recid":"3488","relation_version_is_last":true,"title":["多孔質材料のマルチスケール確率応力解析および信頼性設計法に関する研究"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-21T01:33:53.371403+00:00"}
