When these two simple waves impinge vertically on a free surface, the behavior of the reflected waves is elucidated. In a nonlinear elastic medium, the stress condition is also nonlinear, so that the stress-free surface condition yields usually a variety of the reflected waves for the incidence of the wave. These solutions of the reflected simple waves are obtained for the incidence of the simple waves. Whether the incident simple waves are non-coupled or coupled, the excited reflected wave is a non-coupled simple wave. This excited wave has slow velocity as compared with that of the incident simple waves. The obtained result is very significant in order to interpret the wave behavior at the free surface on the occasion of a direct-hit earthquake.","subitem_description_type":"Abstract"},{"subitem_description":"無限非線形等方性媒質において二種類の単純波すなわち非結合単純波(noncoupled simplewave:縦成分のみの波)と結合単純波(coupled simple wave:縦成分と横成分の結合波)が発生することを筆者は以前の論文で論じた.本論文では,自由表面のある半無限非線形媒質において自由表面直下から真上に上述の単純波が突入したときに自由表面で何が起こるかを解明した.この現象の解明は直下型地震を理解するのに極めて有意義だと考えられる.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"127057","nameIdentifierScheme":"WEKO"}],"names":[{"name":"桃井, 高夫"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000032722","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_4_text_4":{"attribute_name":"著者所属","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":"MOMOI, Takao"}],"nameIdentifiers":[{"nameIdentifier":"127056","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":"ji0681001.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0681001.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32722/files/ji0681001.pdf"},"version_id":"87c90f77-4d1d-4445-a5e2-48a2a81e1cff"}]},"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":"The Waves Excited near the Free Surface in the Half-infinite Nonlinear-elastic Isotropic Medium","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"The Waves Excited near the Free Surface in the Half-infinite Nonlinear-elastic Isotropic Medium","subitem_title_language":"en"}]},"item_type_id":"4","owner":"1","path":["4705","4706"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-05-30"},"publish_date":"2008-05-30","publish_status":"0","recid":"32722","relation_version_is_last":true,"title":["The Waves Excited near the Free Surface in the Half-infinite Nonlinear-elastic Isotropic Medium"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T05:17:19.289480+00:00"}
