Firstly, the mean strain of the deformed material around the indentation \u03b5_\u003cic\u003e, which corresponds to the total strain under the uniaxial stress field, is defined following Tabor\u0027s idea. Secondly, hardness/flow stress ratio C is obtained experimentally for C =9.8 P_m/Y, where Y is in MPa, and formulated for two conditions of material (1) elastic-plastic transient process : C=1.1+(2/3) ln(\u03b5_\u003cic\u003e E_s/Y), (2) ideal-plastic deformation : C=2.9; E_s is the Young\u0027s modulus of a material. Finally, by combining these relations, a method of estimating the flow stress-strain characteristic curve by spherical indentation is proposed. In addition, an example of estimation of the flow stress-strain characteristic curve of SUS 304 is shown over a wide range of strain by means of the proposed method.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_5_full_name_3": {"attribute_name": "\u8457\u8005\u5225\u540d", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "7175", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "\u77f3\u6a4b, \u9054\u5f25", "nameLang": "ja"}]}]}, "item_5_publisher_7": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "THE JAPAN SOCIETY OF MECHANICAL ENGINEERS", "subitem_publisher_language": "en"}]}, "item_5_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "http://doi.org/10.1299/jsmea1988.31.1_117", "subitem_relation_type_select": "DOI"}}]}, "item_5_select_19": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_5_source_id_11": {"attribute_name": "\u66f8\u8a8c\u30ec\u30b3\u30fc\u30c9ID", "attribute_value_mlt": [{"subitem_source_identifier": "AA10680585", "subitem_source_identifier_type": "NCID"}]}, "item_5_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0914-8809", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Ishibashi, Tatsuya", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "7173", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Shimoda, Shigeru", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "7174", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-07-29"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "7_0001.pdf", "filesize": [{"value": "1.2 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1200000.0, "url": {"label": "7_0001.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/2140/files/7_0001.pdf"}, "version_id": "1c15e6f8-826b-4539-9ebe-e87e6e0cfb2d"}]}, "item_keyword": {"attribute_name": "\u30ad\u30fc\u30ef\u30fc\u30c9", "attribute_value_mlt": [{"subitem_subject": "Material Testing", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Hardness", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Mean Contact Pressure", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Total Mean Strain of an Indentation", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Flow Stress", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Hardness", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Flow Stress Ratio", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Stress-Strain Characteristic Curve", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "The Correlation Between Hardness (Mean Contact Pressure by a Spherical Indenter) and Flow Stress", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "The Correlation Between Hardness (Mean Contact Pressure by a Spherical Indenter) and Flow Stress", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["453/454", "423/424/425"], "permalink_uri": "http://hdl.handle.net/10191/1798", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2007-05-10"}, "publish_date": "2007-05-10", "publish_status": "0", "recid": "2140", "relation": {}, "relation_version_is_last": true, "title": ["The Correlation Between Hardness (Mean Contact Pressure by a Spherical Indenter) and Flow Stress"], "weko_shared_id": -1}
