To solve the above points, first the simple theory of rebound hardness is obtained on the basis of three points ; (1) The relative equations of a specimen and a spherical indenter in the elastic-plastic transient indenting process (at the 1st report) are used. (2) To correspond to the various profile of indenters (D type Shore hammer, etc.), the relative equations of rebound energy including the elastic effect of the holding shaft of an indenting sphere (at the 3rd report) are used. (3) The dynamic work necessary to produce a unit volume of the permanent indentation is different quantitatively from the dynamic mean contact pressure. Secondly, the impact experiments are given by the two tip ball type indenters for several specimens, and the necessary expressions are formulated to calculate the concrete values of rebound hardness number. Finally, the experimental results by IIZUKA regarding the influence of the wide conditions of D type Shore hammer on rebound hardness number are quoted and compared with the calculated values using this theory and a good coincidence is obtained between them quantitatively in all points.", "subitem_description_type": "Abstract"}]}, "item_5_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "44770", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Ishibashi, Tatsuya"}]}, {"nameIdentifiers": [{"nameIdentifier": "44771", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Shimoda, Shigeru"}]}, {"nameIdentifiers": [{"nameIdentifier": "44772", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Furukawa, Tooru"}]}, {"nameIdentifiers": [{"nameIdentifier": "44773", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Yoshida, Hidetoshi"}]}]}, "item_5_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "日本機械学会"}]}, "item_5_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "日本機械学会"}]}, "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": "AN0018742X", "subitem_source_identifier_type": "NCID"}]}, "item_5_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "03875008", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "石橋, 達弥"}], "nameIdentifiers": [{"nameIdentifier": "44766", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "下田, 茂"}], "nameIdentifiers": [{"nameIdentifier": "44767", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "古川, 徹"}], "nameIdentifiers": [{"nameIdentifier": "44768", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "吉田, 秀敏"}], "nameIdentifiers": [{"nameIdentifier": "44769", "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_0003.pdf", "filesize": [{"value": "993.3 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 993300.0, "url": {"label": "3_0003.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/3699/files/3_0003.pdf"}, "version_id": "a402a8c3-0fdb-4f16-a11b-08f7d53d235e"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Material Testing", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Theory of Rebound Hardness", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Impact", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Spherical Indenter", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Dynamic Mean Plastic Flow Pressure", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Dynamic Mean Contact Pressure", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Dynamic Mean Pressure Ratio", "subitem_subject_scheme": "Other"}, {"subitem_subject": "D Type Shore Hardness Number", "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": "球圧子による反発硬さ理論(反発硬さ数に及ぼす圧子・試料条件の影響)", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "球圧子による反発硬さ理論(反発硬さ数に及ぼす圧子・試料条件の影響)"}, {"subitem_title": "球圧子による反発硬さ理論(反発硬さ数に及ぼす圧子・試料条件の影響)", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "425"], "permalink_uri": "http://hdl.handle.net/10191/1766", "pubdate": {"attribute_name": "公開日", "attribute_value": "2007-05-10"}, "publish_date": "2007-05-10", "publish_status": "0", "recid": "3699", "relation": {}, "relation_version_is_last": true, "title": ["球圧子による反発硬さ理論(反発硬さ数に及ぼす圧子・試料条件の影響)"], "weko_shared_id": null}
