However, due mainly to a rectangular incident stress pulse with a short rising time, the strain rate becomes considerably higher when a difference in mechanical impedance between a specimen and the pressure bars is large. This tendency may be enhanced when determining strength of specimen because the incident pulse amplitude must be high enough to break a specimen. In this study, stepped and tapered striker bars were proposed to increase the rising time of incident stress pulse. A simple procedure was developed for simulating an incident stress pulse profile generated by a striker bar with variable cross section. Validation was done by comparing predicted incident stress pulse profiles of uniform, 5-stepped and tapered striker bars with those obtained by longitudinal impact experiments. In addition, four kinds of polymer specimens were tested by the three kinds of striker bars. Results showed that the strain rates at failure obtained by the 5-stepped and tapered striker bars were remarkably lower than that obtained by the uniform striker bar regardless of the material properties of specimen.", "subitem_description_type": "Abstract"}]}, "item_5_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "40031", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Kobayashi, Koichi"}]}, {"nameIdentifiers": [{"nameIdentifier": "40032", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Tanabe, Yuji"}]}]}, "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/jjsem2001/2/2/2_2_117/_pdf", "subitem_relation_type_select": "URI"}}]}, "item_5_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "Copyright (C) 2002 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": "40029", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "田邊, 裕治"}], "nameIdentifiers": [{"nameIdentifier": "40030", "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": "2_2_117-121.pdf", "filesize": [{"value": "660.4 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 660400.0, "url": {"label": "2_2_117-121.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/2945/files/2_2_117-121.pdf"}, "version_id": "25e00ab1-bf51-4c16-99e2-b617aa1311f0"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Impact Testing", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Split-Hopkinson Pressure-Bar Test", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Bar with Variable Cross Section", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Strain Rate", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Polymer", "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": "変断面打撃棒を用いたホプキンソン棒法衝撃試験", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "変断面打撃棒を用いたホプキンソン棒法衝撃試験"}, {"subitem_title": "変断面打撃棒を用いたホプキンソン棒法衝撃試験", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "425"], "permalink_uri": "http://hdl.handle.net/10191/26409", "pubdate": {"attribute_name": "公開日", "attribute_value": "2014-03-17"}, "publish_date": "2014-03-17", "publish_status": "0", "recid": "2945", "relation": {}, "relation_version_is_last": true, "title": ["変断面打撃棒を用いたホプキンソン棒法衝撃試験"], "weko_shared_id": null}
