This phenomenon can be explained by the increase in the crack resistance with crack propagation. This R-curve behavior is caused mainly by grain bridging in the wake of the crack. Recently the grain-bridging stresses for alumina and silicon nitride have been measured experimentally. In this study, the fracture strength is estimated by numerical simulation, based on grain-bridging stresses. In the simulation, the effective stress intensity factor at the crack tip, K_<tip>, and the effective fracture toughness at the crack tip, (K_<tip>)_c, are used for the conditions of stable and unstable crack propagation. It is found that the fracture toughness for long cracks, K_<Ic>, depends on specimen geometries, and the maximum values of K_c approach (K_<tip>)_c as the initial crack length approaches the width of the specimen. Furthermore a convenient method to evaluate (K_<tip>)_c experimentally is discussed.","subitem_description_type":"Other"}]},"item_16_description_77":{"attribute_name":"URL","attribute_value_mlt":[{"subitem_description":"http://ci.nii.ac.jp/naid/110002371861@@@http://www.jsme.or.jp","subitem_description_type":"Other"}]},"item_16_publisher_36":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"社団法人 日本機械学会"}]},"item_16_relation_16":{"attribute_name":"情報源(ISSN)","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"03875008"}]}]},"item_16_relation_64":{"attribute_name":"別フォーマットである","attribute_value_mlt":[{"subitem_relation_type":"isFormatOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://hdl.handle.net/2298/13052","subitem_relation_type_select":"URI"}}]},"item_16_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"社団法人 日本機械学会"}]},"item_16_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN0018742X","subitem_source_identifier_type":"NCID"}]},"item_16_subject_20":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"530","subitem_subject_scheme":"NDC"}]},"item_16_text_18":{"attribute_name":"形態","attribute_value_mlt":[{"subitem_text_value":"593010 bytes"}]},"item_16_text_37":{"attribute_name":"出版者（ヨミ）","attribute_value_mlt":[{"subitem_text_value":"ニホン キカイ ガッカイ"}]},"item_16_text_38":{"attribute_name":"別言語の出版者","attribute_value_mlt":[{"subitem_text_value":"The Japan Society of Mechanical Engineers"}]},"item_16_text_47":{"attribute_name":"資源タイプ・ローカル","attribute_value_mlt":[{"subitem_text_value":"雑誌掲載論文"}]},"item_16_text_48":{"attribute_name":"資源タイプ・NII","attribute_value_mlt":[{"subitem_text_value":"Journal Article"}]},"item_16_text_49":{"attribute_name":"資源タイプ・DCMI","attribute_value_mlt":[{"subitem_text_value":"text"}]},"item_16_text_50":{"attribute_name":"資源タイプ・ローカル表示コード","attribute_value_mlt":[{"subitem_text_value":"01"}]},"item_16_text_78":{"attribute_name":"コメント","attribute_value_mlt":[{"subitem_text_value":"本文データは学協会の許諾に基づきCiNiiから複製したものである"},{"subitem_text_value":"第2報は、関連を参照のこと。"}]},"item_16_version_type_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"森, 和也"}],"nameIdentifiers":[{"nameIdentifier":"100312","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"野口, 博司"}],"nameIdentifiers":[{"nameIdentifier":"100313","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tabarrok, Berouz"}],"nameIdentifiers":[{"nameIdentifier":"100314","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":"2020-03-02"}],"displaytype":"detail","filename":"110002371861.pdf","filesize":[{"value":"593.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"110002371861.pdf","url":"https://kumadai.repo.nii.ac.jp/record/22988/files/110002371861.pdf"},"version_id":"43221f95-6e26-41a0-bb71-7d1075dffeac"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Ceramics","subitem_subject_scheme":"Other"},{"subitem_subject":"Fracture Toughness","subitem_subject_scheme":"Other"},{"subitem_subject":"Stress Intensity Factor","subitem_subject_scheme":"Other"},{"subitem_subject":"Fracture Mechanics","subitem_subject_scheme":"Other"},{"subitem_subject":"Body Force Method","subitem_subject_scheme":"Other"},{"subitem_subject":"Fracture Strength","subitem_subject_scheme":"Other"},{"subitem_subject":"Defect","subitem_subject_scheme":"Other"},{"subitem_subject":"Effective Fracture Toughness at Crack Tip","subitem_subject_scheme":"Other"},{"subitem_subject":"Effective Stress Intensity Factor at Crack Tip","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":"数値シミュレーションによる欠陥を有するセラミックスの破壊強度評価 : 第1報,基礎理論とアルミナセラミックスへの応用","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"数値シミュレーションによる欠陥を有するセラミックスの破壊強度評価 : 第1報,基礎理論とアルミナセラミックスへの応用"}]},"item_type_id":"16","owner":"1","path":["428"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-11-11"},"publish_date":"2009-11-11","publish_status":"0","recid":"22988","relation_version_is_last":true,"title":["数値シミュレーションによる欠陥を有するセラミックスの破壊強度評価 : 第1報,基礎理論とアルミナセラミックスへの応用"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-19T18:47:31.808056+00:00"}
