The railway ballast layer is modeled by 3-D or 2-D plane strain finite elements. The constitutive relation of the railway ballast is defined using the cyclic densification model. The model calibration is carried out in comparison with the cyclic loading test data on a full-scale ballasted track reported by Ishikawa et al. For the 3-D simulation, the load-displacement curve in loading process at the 1st cycle is comparable to one of the test results. The accumulated displacement at the top of the sleeper can be predicted with high accuracy; the simulated accumulation rate is higher than one of the test results. The 2-D plane strain FE analysis is attempted to reduce the computational cost for predicting the full-scale ballast settlement analysis. The plane strain approximation with respect to the longitudinal section of a track is valid to evaluate the stress, strain and displacement in the ballast layer.","subitem_description_type":"Abstract"}]},"item_5_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"41660","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Sato, Emi"}]},{"nameIdentifiers":[{"nameIdentifier":"41661","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Koro, Kazuhiro"}]},{"nameIdentifiers":[{"nameIdentifier":"41662","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Abe, Kazuhisa"}]}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"土木学会"}]},"item_5_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright(C)2013 公益社団法人土木学会"}]},"item_5_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"佐藤, 江美"}],"nameIdentifiers":[{"nameIdentifier":"41657","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"紅露, 一寛"}],"nameIdentifiers":[{"nameIdentifier":"41658","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"阿部, 和久"}],"nameIdentifiers":[{"nameIdentifier":"41659","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-07-30"}],"displaytype":"detail","filename":"17_143-150.pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"17_143-150.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/3247/files/17_143-150.pdf"},"version_id":"99d33efe-bd19-4ab0-8312-710f40b7c4ce"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"railway ballast","subitem_subject_scheme":"Other"},{"subitem_subject":"ballast settlement","subitem_subject_scheme":"Other"},{"subitem_subject":"cyclic densification model","subitem_subject_scheme":"Other"},{"subitem_subject":"FEM","subitem_subject_scheme":"Other"},{"subitem_subject":"plane strain","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":"Cyclic densificationモデルを用いた有限要素法に基づくバラスト道床沈下解析法の適用可能性に関する検討","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Cyclic densificationモデルを用いた有限要素法に基づくバラスト道床沈下解析法の適用可能性に関する検討"},{"subitem_title":"Cyclic densificationモデルを用いた有限要素法に基づくバラスト道床沈下解析法の適用可能性に関する検討","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","470"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-12-17"},"publish_date":"2014-12-17","publish_status":"0","recid":"3247","relation_version_is_last":true,"title":["Cyclic densificationモデルを用いた有限要素法に基づくバラスト道床沈下解析法の適用可能性に関する検討"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:36:23.266409+00:00"}
