Gamma irradiation was performed at 30kGy in nitrogen or at 29kGy in air without post-irradiation treatment. Impact compressive tests using the split-Hopkinson pressure-bar (SHPB) technique were performed to measure stress\u2013strain relations up to a true strain of 8% at a strain rate of 260s-1. Gamma irradiation in air significantly increased the Young\u0027s modulus and the 0.5% yield stress, and gamma irradiation in N2 significantly increased the 0.5% yield stress, as determined by impact compressive testing. The impact stress-strain behaviors of both unirradiated and gamma irradiated UHMWPE specimens were compared by the elasto-viscoplastic model proposed by Bergstr\u00f6m [Biomaterials Vol.23 p.2329 (2002)]. We found that the elasto-viscoplastic model had a potential to predict the observed impact stress-strain responses.", "subitem_description_type": "Abstract"}]}, "item_5_full_name_3": {"attribute_name": "\u8457\u8005\u5225\u540d", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "39709", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Kobayashi, Koichi"}]}, {"nameIdentifiers": [{"nameIdentifier": "39710", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Sakamoto, Makoto"}]}, {"nameIdentifiers": [{"nameIdentifier": "39711", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Tanabe, Yuji"}]}]}, "item_5_publisher_7": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "\u65e5\u672c\u6750\u6599\u5b66\u4f1a"}]}, "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": "AN00096175", "subitem_source_identifier_type": "NCID"}]}, "item_5_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "05145163", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "\u5c0f\u6797, \u516c\u4e00"}], "nameIdentifiers": [{"nameIdentifier": "39706", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "\u5742\u672c, \u4fe1"}], "nameIdentifiers": [{"nameIdentifier": "39707", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "\u7530\u908a, \u88d5\u6cbb"}], "nameIdentifiers": [{"nameIdentifier": "39708", "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": "2019-07-30"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "ZQ_57(9)_882-886.pdf", "filesize": [{"value": "646.5 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 646500.0, "url": {"label": "ZQ_57(9)_882-886.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/2909/files/ZQ_57(9)_882-886.pdf"}, "version_id": "01493457-9bad-4286-9cb4-b34605274858"}]}, "item_keyword": {"attribute_name": "\u30ad\u30fc\u30ef\u30fc\u30c9", "attribute_value_mlt": [{"subitem_subject": "Biomaterials", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Biomechanics", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Ultra-high molecular-weight polyethylene", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Hopkinson-bar Technique", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Inelastic deformation", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Gamma irradiation", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Constitutive equation", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "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": "\u8d85\u5206\u5b50\u91cf\u30dd\u30ea\u30a8\u30c1\u30ec\u30f3\u306e\u885d\u6483\u5727\u7e2e\u7279\u6027\u306b\u53ca\u307c\u3059\u4f4e\u30ac\u30f3\u30de\u7dda\u7167\u5c04\u306e\u5f71\u97ff\u3068\u69cb\u6210\u5247\u306e\u691c\u8a0e", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "\u8d85\u5206\u5b50\u91cf\u30dd\u30ea\u30a8\u30c1\u30ec\u30f3\u306e\u885d\u6483\u5727\u7e2e\u7279\u6027\u306b\u53ca\u307c\u3059\u4f4e\u30ac\u30f3\u30de\u7dda\u7167\u5c04\u306e\u5f71\u97ff\u3068\u69cb\u6210\u5247\u306e\u691c\u8a0e"}, {"subitem_title": "\u8d85\u5206\u5b50\u91cf\u30dd\u30ea\u30a8\u30c1\u30ec\u30f3\u306e\u885d\u6483\u5727\u7e2e\u7279\u6027\u306b\u53ca\u307c\u3059\u4f4e\u30ac\u30f3\u30de\u7dda\u7167\u5c04\u306e\u5f71\u97ff\u3068\u69cb\u6210\u5247\u306e\u691c\u8a0e", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["453/454", "506/507/508"], "permalink_uri": "http://hdl.handle.net/10191/17661", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2012-04-05"}, "publish_date": "2012-04-05", "publish_status": "0", "recid": "2909", "relation": {}, "relation_version_is_last": true, "title": ["\u8d85\u5206\u5b50\u91cf\u30dd\u30ea\u30a8\u30c1\u30ec\u30f3\u306e\u885d\u6483\u5727\u7e2e\u7279\u6027\u306b\u53ca\u307c\u3059\u4f4e\u30ac\u30f3\u30de\u7dda\u7167\u5c04\u306e\u5f71\u97ff\u3068\u69cb\u6210\u5247\u306e\u691c\u8a0e"], "weko_shared_id": null}
