Thus, it is very important to investigate the development of lattice defects through grain boundaries, which is closely related with the anomalous mechanical characteristics of BNMs. In this study, the development of\u2028complicated interior lattice defects in BNMs was expressed by the large-scale calculation by the atomistic model which can directly express atomic structure of grain boundary (molecular dynamics) and the continuum modeling considering the effect of grain boundaries (crystal plasticity theory), and we investigated the grain size dependence of the following phenomena: (1) dislocation emissions from grain boundaries, (2) the crack tip plasticity based on the interaction between dislocations and grain boundaries, and (3) the propagation mechanism of the plastic deformation based on the formation and dissipation of lattice defects.","subitem_description_type":"Abstract"}]},"item_9_description_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号:22102007, 研究期間(年度):2010-04-01 - 2015-03-31","subitem_description_type":"Other"},{"subitem_description":"出典：「内部欠陥構造発展の大規模計算によるバルクナノメタルの力学特性解析」研究成果報告書　課題番号22102007\n（KAKEN：科学研究費助成事業データベース（国立情報学研究所）） \n（https://kaken.nii.ac.jp/report/KAKENHI-PLANNED-22102007/22102007seika/）を加工して作成","subitem_description_type":"Other"}]},"item_9_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学理工研究域機械工学系","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00052692","subitem_identifier_reg_type":"JaLC"}]},"item_9_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/search/?qm=40361977"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/search/?qm=40361977","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PLANNED-22102007/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PLANNED-22102007/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/report/KAKENHI-PLANNED-22102007/22102007seika/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/report/KAKENHI-PLANNED-22102007/22102007seika/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/grant/KAKENHI-AREA-2201/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/grant/KAKENHI-AREA-2201/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/en/grant/KAKENHI-AREA-2201/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/en/grant/KAKENHI-AREA-2201/","subitem_relation_type_select":"URI"}}]},"item_9_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-11-08"}],"displaytype":"detail","filename":"TE-PR-SHIMOKAWA-T-kaken 2015-6p.pdf","filesize":[{"value":"1.6 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"TE-PR-SHIMOKAWA-T-kaken 2015-6p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/46360/files/TE-PR-SHIMOKAWA-T-kaken 2015-6p.pdf"},"version_id":"3b259eb9-31dc-4b69-b250-33d88bc26cc7"}]},"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":"内部欠陥構造発展の大規模計算によるバルクナノメタルの力学特性解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"内部欠陥構造発展の大規模計算によるバルクナノメタルの力学特性解析"},{"subitem_title":"Analysis of mechanical properties of bulk nanostructured metals by large-scale computing on the defects evolution","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["2819"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-11-08"},"publish_date":"2018-11-08","publish_status":"0","recid":"46360","relation_version_is_last":true,"title":["内部欠陥構造発展の大規模計算によるバルクナノメタルの力学特性解析"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-07-27T09:35:26.829312+00:00"}
