And it was found that the results obtained by different methods scattered largely and showed very poor coincidence. Reasons for such big difference in the results of the measurement of adhesive properties are discussed analytically in this report. In the case of single particle measurement, the effects of the direction of separation force and the contact relation of particles are pointed out and new equations including these effects are proposed. In the case of podwer bed, the effect of compression force at the contact point is pointed out as one of the most essential factors which determine the strength of powder bed. Then based on the experimental finding about the relation between the tensile strength and the porosity of powder bed, modified Rumpf s equation is derived semitheoretically and proposed here taking into account of the effect of compression force. Other measurement methods and their results of adhesive properties, such as deagglomeration of agglomerated powder assemblage in air stream and the change of adhesion force against temperature, are also shown. The latter are applied to the analysis of fluidized bed for predicting the incipient fluidization velocity at elevated temperature. Finally time-dependent properties, such as fatigue and creep, are proposed as new characterizing principles of powder materials. With all these results obtained experimentally and theoretically, the main causes of big difference of measured results of adhesion force by different methods are explained qualitatively.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_9_identifier_registration": {"attribute_name": "ID登録", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.18999/memfenu.40.1.1", "subitem_identifier_reg_type": "JaLC"}]}, "item_9_publisher_32": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Faculty of Engineering, Nagoya University", "subitem_publisher_language": "en"}]}, "item_9_select_15": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_9_source_id_7": {"attribute_name": "ISSN（print）", "attribute_value_mlt": [{"subitem_source_identifier": "0027-7657", "subitem_source_identifier_type": "PISSN"}]}, "item_access_right": {"attribute_name": "アクセス権", "attribute_value_mlt": [{"subitem_access_right": "open access", "subitem_access_right_uri": "http://purl.org/coar/access_right/c_abf2"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Jimbo, Genji", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "101978", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Yamazaki, Ryohei", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "101979", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Tsubaki, Jun-Ichiro", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "101980", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kamiya, Hidehiro", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "101981", "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": "2020-10-29"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "40-1-01.pdf", "filesize": [{"value": "4.9 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 4900000.0, "url": {"label": "40-1-01.pdf", "objectType": "fulltext", "url": "https://nagoya.repo.nii.ac.jp/record/30744/files/40-1-01.pdf"}, "version_id": "8037ed0b-da99-4241-8abf-00eaa02998b3"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "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": "Development of measuring and characterizing methods of mechanical properties of powder particles", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Development of measuring and characterizing methods of mechanical properties of powder particles", "subitem_title_language": "en"}]}, "item_type_id": "9", "owner": "1", "path": ["2552"], "permalink_uri": "https://doi.org/10.18999/memfenu.40.1.1", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2020-10-29"}, "publish_date": "2020-10-29", "publish_status": "0", "recid": "30744", "relation": {}, "relation_version_is_last": true, "title": ["Development of measuring and characterizing methods of mechanical properties of powder particles"], "weko_shared_id": -1}
