Gamma irradiation was performed at 30 kGy in nitrogen or at 29 kGy in air without post-irradiation treatment. Quasi-static and impact compressive tests using the split-Hopkinson pressure-bar technique were performed to measure stress-strain relations up to a true strain of 8% at strain rates of between 0.0004 and 260 s(-1). For both unirradiated and gamma-irradiated UHMWPE specimens, an increase in the strain rate significantly increased the Young's modulus and the 0.5% yield stress. Gamma irradiation in air significantly increased the Young's modulus, as determined by quasi-static and impact compressive testing, and the 0.5% yield stress, as determined by impact compressive testing. The strain-rate dependence in the power-law relationship was similar to that observed for strain rates ranging from 0.02 to 0.10 s(-1) (Kurtz et al., Biomaterials 23, 2002, pp. 3681-3697).","subitem_description_type":"Abstract"}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"IOS Press"}]},"item_5_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright (C) 2007 IOS Press"}]},"item_5_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_5_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA1076721X","subitem_source_identifier_type":"NCID"}]},"item_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09592989","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Kobayashi, Koichi"}],"nameIdentifiers":[{"nameIdentifier":"4286","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kakinoki, Toshihiko"}],"nameIdentifiers":[{"nameIdentifier":"4287","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sakamoto, Makoto"}],"nameIdentifiers":[{"nameIdentifier":"4288","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tanabe, Yuji"}],"nameIdentifiers":[{"nameIdentifier":"4289","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":"2019-07-29"}],"displaytype":"detail","filename":"17_2_87-95.pdf","filesize":[{"value":"146.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"17_2_87-95.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/1558/files/17_2_87-95.pdf"},"version_id":"aee9a2d6-dcb5-4e2e-a83f-18f1cc57097f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Gamma irradiation","subitem_subject_scheme":"Other"},{"subitem_subject":"impact compressive testing","subitem_subject_scheme":"Other"},{"subitem_subject":"strain rate","subitem_subject_scheme":"Other"},{"subitem_subject":"ultra-high molecular-weight polyethylene","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"The effects of strain rate and low-gamma irradiation on the compressive properties of UHMWPE","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"The effects of strain rate and low-gamma irradiation on the compressive properties of UHMWPE"},{"subitem_title":"The effects of strain rate and low-gamma irradiation on the compressive properties of UHMWPE","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","425"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-03-17"},"publish_date":"2014-03-17","publish_status":"0","recid":"1558","relation_version_is_last":true,"title":["The effects of strain rate and low-gamma irradiation on the compressive properties of UHMWPE"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:34:09.977121+00:00"}
