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\u0027s modulus and the 0.5% yield stress. Gamma irradiation in air significantly increased the Young\u0027s 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": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "IOS Press"}]}, "item_5_rights_15": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "Copyright (C) 2007 IOS Press"}]}, "item_5_select_19": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_5_source_id_11": {"attribute_name": "\u66f8\u8a8c\u30ec\u30b3\u30fc\u30c9ID", "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": "\u8457\u8005", "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": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-07-29"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "17_2_87-95.pdf", "filesize": [{"value": "146.2 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 146200.0, "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": "\u30ad\u30fc\u30ef\u30fc\u30c9", "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": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "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": "\u30bf\u30a4\u30c8\u30eb", "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": ["453/454", "423/424/425"], "permalink_uri": "http://hdl.handle.net/10191/26386", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2014-03-17"}, "publish_date": "2014-03-17", "publish_status": "0", "recid": "1558", "relation": {}, "relation_version_is_last": true, "title": ["The effects of strain rate and low-gamma irradiation on the compressive properties of UHMWPE"], "weko_shared_id": null}
