The deformation mechanism has been analyzed by postulating the equivalence of plastic work or an effective strain-hardening relationship, which is based on Prandtl-Reuss’s flow rule and von Mises yield condition. In this paper in order to examine the validity of the hypothesis under the conditions of machining, a special torsional Hopkinson-bar testing machine is designed and constructed. A preliminary experiment shows that the torsional flow stress, which is transformed into compressive stress by using the hypothesis, does not necessarily coincide with the compressive data for 0.19％C carbon steel, when the effective strain exceeds around 0.4 at a temperature of 673 K and a strain rate of 1000 s^\u003c-1\u003e. The agreement can be seen up to larger strains at higher temperatures and/or lower strain rate deformations. The range of strains, which validates the hypothesis, decreases in the order aluminum alloy，0.19％C carbon steel, commercial zinc.", "subitem_description_type": "Abstract"}]}, "item_2_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "33036", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Katsuhiro, MAEKAWA"}]}, {"nameIdentifiers": [{"nameIdentifier": "33037", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Akihiko, KUBO"}]}, {"nameIdentifiers": [{"nameIdentifier": "33038", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Takeaki, KITAGAWA"}]}]}, "item_2_publisher_32": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "北見工業大学"}]}, "item_2_select_15": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "前川, 克廣"}], "nameIdentifiers": [{"nameIdentifier": "33033", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "久保, 明彦"}], "nameIdentifiers": [{"nameIdentifier": "44823", "nameIdentifierScheme": "WEKO"}, {"nameIdentifier": "1000040178025 ", "nameIdentifierScheme": "NRID", "nameIdentifierURI": "http://rns.nii.ac.jp/d/nr/1000040178025 "}]}, {"creatorNames": [{"creatorName": "北川, 武揚"}], "nameIdentifiers": [{"nameIdentifier": "33035", "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": "2016-11-22"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "15-1-1.pdf", "filesize": [{"value": "8.9 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 8900000.0, "url": {"label": "15-1-1.pdf", "url": "https://kitami-it.repo.nii.ac.jp/record/6549/files/15-1-1.pdf"}, "version_id": "6a44175d-cdac-400e-9310-159f954be06e"}]}, "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": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "高温・高ひずみ速度変形における塑性仕事の等価性の検討 （第1報）-ホプキンソン棒法衝撃ねじり試験機の試作と単純負荷の場合-", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "高温・高ひずみ速度変形における塑性仕事の等価性の検討 （第1報）-ホプキンソン棒法衝撃ねじり試験機の試作と単純負荷の場合-"}]}, "item_type_id": "2", "owner": "1", "path": ["36"], "permalink_uri": "https://kitami-it.repo.nii.ac.jp/records/6549", "pubdate": {"attribute_name": "公開日", "attribute_value": "2007-04-09"}, "publish_date": "2007-04-09", "publish_status": "0", "recid": "6549", "relation": {}, "relation_version_is_last": true, "title": ["高温・高ひずみ速度変形における塑性仕事の等価性の検討 （第1報）-ホプキンソン棒法衝撃ねじり試験機の試作と単純負荷の場合-"], "weko_shared_id": 3}
