Pressure dependence of strength is very different for different types of fractures and continuously changes from a brittle stage to a ductile stage. Average strength-pressure curves of each rock type are estimated. A simple rule for transition from brittle fracture to ductile flow is found. The transition rule is different between silicate rocks and carbonate rocks, this being attributed to different transition mechanisms in each case.","subitem_description_type":"Abstract"},{"subitem_description":"岩石の破壊強度と圧力の関係については,従来,脆性破壊に関するCoulomb law,延性破壊に関するMaximum Shear Stress Criterionが適用されると考えられてきた.しかし,本論文で多くの岩石の強度-圧力関係はこの様な単純な直線関係からはほど遠いものであることを示した.強度-圧力曲線は著しく彎曲し,脆性破壊領域から延性破壊領域へ徐々にその傾斜を減じ乍らうつりかわつている.すなわち,岩石強度の圧力依存性は,脆性-延性遷移過程を考慮することによつてはじめて統一的に理解される.また,脆性から延性への遷移条件について1つの簡単な法則が見出され,これにもとづいて遷移の機構を考察した.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"131259","nameIdentifierScheme":"WEKO"}],"names":[{"name":"茂木, 清夫"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000033594","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学地震研究所"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00162258","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00408972","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"453","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"Earthquake Research Institute, University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Mogi, Kiyoo"}],"nameIdentifiers":[{"nameIdentifier":"131258","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":"2017-06-26"}],"displaytype":"detail","filename":"ji0441012.pdf","filesize":[{"value":"881.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0441012.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/33594/files/ji0441012.pdf"},"version_id":"9dbc330d-1c07-497f-a03f-ecc1cc760ebb"}]},"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":"Pressure Dependence of Rock Strength and Transition from Brittle Fracture to Ductile Flow","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Pressure Dependence of Rock Strength and Transition from Brittle Fracture to Ductile Flow","subitem_title_language":"en"}]},"item_type_id":"4","owner":"1","path":["4945","4946"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-05-30"},"publish_date":"2008-05-30","publish_status":"0","recid":"33594","relation_version_is_last":true,"title":["Pressure Dependence of Rock Strength and Transition from Brittle Fracture to Ductile Flow"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T04:38:41.522227+00:00"}
