To clarify that point, we indented steel and tungsten-carbide spherical indenters in the several standard blocks for hardness. In order to establish the relations of the elastic-plastic transient indenting process experimentally we related the hardness P_m(mean contact pressure) with a true profile coefficient of the permanent indentation : (d/D_p), not with an apparent profile coefficient : (d/D) used traditionally, and formulated as follows ; P_m=P_\u003cup\u003e(d/D_p)^\u003cxp\u003e. We can calculate the hardness affected by the different mechanical properties of the spherical indenter using this formula for arbitrary conditions. Further, we compared the Brinell hardness obtained by Yoshizawa with our calculated values, and we obtained a good coincidence between them.", "subitem_description_type": "Abstract"}]}, "item_5_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "44784", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Ishibashi, Tatsuya"}]}, {"nameIdentifiers": [{"nameIdentifier": "44785", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Shimoda, Shigeru"}]}]}, "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": "44782", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "下田, 茂"}], "nameIdentifiers": [{"nameIdentifier": "44783", "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_0006.pdf", "filesize": [{"value": "846.1 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 846100.0, "url": {"label": "3_0006.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/3702/files/3_0006.pdf"}, "version_id": "ee6c1f0a-90de-4135-9a2b-9487dbb6f389"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Material Testing", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Mechanical Property", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Hardness", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Mean Contact Pressure", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Elastic-Plastic Transient Area", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Profile Coefficient of Indentation", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Spherical Indenter", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Brinell Hardness", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Deformation of Indenter", "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": "圧子球材質の相違が硬さに及ぼす影響", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "圧子球材質の相違が硬さに及ぼす影響"}, {"subitem_title": "圧子球材質の相違が硬さに及ぼす影響", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "425"], "permalink_uri": "http://hdl.handle.net/10191/1769", "pubdate": {"attribute_name": "公開日", "attribute_value": "2007-05-10"}, "publish_date": "2007-05-10", "publish_status": "0", "recid": "3702", "relation": {}, "relation_version_is_last": true, "title": ["圧子球材質の相違が硬さに及ぼす影響"], "weko_shared_id": null}
