The starting point of the theory is the strain energy of SWNTs predicted by\nab initio calculations based on the density functional theory DFT, which shows the same behavior as that\nobtained for the continuum elastic shell model. We extend this result for inflated SWNTs with circular cross\nsection to calculate the deformation energy of a deformed SWNT without performing further DFT calculations.\nThis extension is then complemented by a van der Waals interaction, which is not fully taken into account in\nthe DFT approximations currently in use but becomes important in highly deformed tubes. We find that the\nminimum pressure, P1, for the radial deformation to occur is proportional to the inverse cube of tube diameter,\nD, in agreement with the recent theoretical predictions as well as the classical theory of buckling. The radial\ndeformation of SWNTs with D2.5 nm is found to be elastic up to very high pressure and they hardly\ncollapse. On the other hand, SWNTs with D2.5 nm show a plastic deformation and collapse if the applied\nhydrostatic pressure exceeds a critical value, which is about 30–40% higher than P1 and also varies as D−3\nthough approximately. These SWNTs with large D collapse when the cross-sectional area is about 60% reduced\nwith respect to the circular one. It is also found that for SWNTs with D7.0 nm, the plastically deformed\ncollapsed state is more stable than the inflated one. This critical value of D is somewhat larger than previously\npredicted.","subitem_description_type":"Other"}]},"item_16_publisher_14":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"American Physical Society"}]},"item_16_relation_26":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1103/PhysRevB.74.115401","subitem_relation_type_select":"DOI"}}]},"item_16_rights_18":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2006 The American Physical Society"}]},"item_16_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1098-0121","subitem_source_identifier_type":"ISSN"}]},"item_16_text_4":{"attribute_name":"著者(機関)","attribute_value_mlt":[{"subitem_text_value":"Faculty of Engineering, Iwate University"}]},"item_16_version_type_27":{"attribute_name":"著者版フラグ","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":"Hasegawa, Masayuki"}],"nameIdentifiers":[{"nameIdentifier":"61538","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nishidate, Kazume"}],"nameIdentifiers":[{"nameIdentifier":"61539","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":"2016-11-14"}],"displaytype":"detail","filename":"prb-v74i11p115401.pdf","filesize":[{"value":"683.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"prb-v74i11p115401.pdf","url":"https://iwate-u.repo.nii.ac.jp/record/9907/files/prb-v74i11p115401.pdf"},"version_id":"ae2427c1-8e58-48d4-80d7-d5f327aa9aa4"}]},"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":"Radial deformation and stability of single-wall carbon nanotubes under hydrostatic pressure","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Radial deformation and stability of single-wall carbon nanotubes under hydrostatic pressure"}]},"item_type_id":"16","owner":"3","path":["1519"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-02-09"},"publish_date":"2010-02-09","publish_status":"0","recid":"9907","relation_version_is_last":true,"title":["Radial deformation and stability of single-wall carbon nanotubes under hydrostatic pressure"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T11:52:57.151796+00:00"}
