Ten cylindrical specimens, 8mm in both diameter and length, were machined from compression molded UHMWPE rods. Half of these specimens were gamma-irradiated in air at a dose of 2.9 Mrad without post irradiation treatment. Impact compression tests were performed using the split-Hopkinson pressure-bar technique to evaluate dynamic stress-strain relation up to 8% strain at a strain rate of about 400s-1. For both gamma-irradiated and unirradiated specimens, stress-strain relations exhibited relatively linear portions up to 2% strains and the gradients eventually decreased with increasing strain. Young\u0027s modulus determined from the linear portion and 0.5% yield stress were significantly higher for gamma-irradiated specimens than for unirradiated specimens. Two-dimensional elasto-plastic stress and strain analysis of hip prosthesis was performed under impact loading using a finite element method. Results indicated that the increase in mechanical properties induced by gamma irradiation reduced plastic strain within the UHMWPE cup.", "subitem_description_type": "Abstract"}]}, "item_5_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "40023", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Kobayashi, Koichi"}]}, {"nameIdentifiers": [{"nameIdentifier": "40024", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Kakinoki, Toshihiko"}]}, {"nameIdentifiers": [{"nameIdentifier": "40025", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Tanabe, Yuji"}]}, {"nameIdentifiers": [{"nameIdentifier": "40026", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Sakamoto, Makoto"}]}]}, "item_5_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "日本実験力学会"}]}, "item_5_relation_31": {"attribute_name": "異版である", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "https://www.jstage.jst.go.jp/article/jjsem2001/3/4/3_4_225/_pdf", "subitem_relation_type_select": "URI"}}]}, "item_5_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "Copyright (C) 2003 JSEM"}, {"subitem_rights": "コンテンツのご利用は著作権法の範囲内でお願いします。"}, {"subitem_rights": "本文データは学協会の許諾に基づきJ-Stageから複製したものである"}]}, "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": "AA11822914", "subitem_source_identifier_type": "NCID"}]}, "item_5_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "13464930", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "小林, 公一"}], "nameIdentifiers": [{"nameIdentifier": "40019", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "柿木, 俊彦"}], "nameIdentifiers": [{"nameIdentifier": "40020", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "田邊, 裕治"}], "nameIdentifiers": [{"nameIdentifier": "40021", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "坂本, 信"}], "nameIdentifiers": [{"nameIdentifier": "40022", "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": "2019-07-30"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "3_4_225-229.pdf", "filesize": [{"value": "924.2 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 924200.0, "url": {"label": "3_4_225-229.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/2943/files/3_4_225-229.pdf"}, "version_id": "055cfc79-bce7-4fab-b6ec-8963d96a35c1"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Biomechanics", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Ultra-High Molecular-Weight Polyethylene", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Split-Hopkinson Pressure-Bar Test", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Gamma Irradiation Sterilization", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Total Hip Joint Arthroplasty", "subitem_subject_scheme": "Other"}, {"subitem_subject": "FEM", "subitem_subject_scheme": "Other"}]}, "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": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "超高分子量ポリエチレンの衝撃圧縮特性 : ガンマ線照射による特性変化と人工股関節における動的応力・ひずみ解析", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "超高分子量ポリエチレンの衝撃圧縮特性 : ガンマ線照射による特性変化と人工股関節における動的応力・ひずみ解析"}, {"subitem_title": "超高分子量ポリエチレンの衝撃圧縮特性 : ガンマ線照射による特性変化と人工股関節における動的応力・ひずみ解析", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "425"], "permalink_uri": "http://hdl.handle.net/10191/26408", "pubdate": {"attribute_name": "公開日", "attribute_value": "2014-03-17"}, "publish_date": "2014-03-17", "publish_status": "0", "recid": "2943", "relation": {}, "relation_version_is_last": true, "title": ["超高分子量ポリエチレンの衝撃圧縮特性 : ガンマ線照射による特性変化と人工股関節における動的応力・ひずみ解析"], "weko_shared_id": null}
