The received signal is analyzed by the wavelet transform to identify the mode of the guided wave using group velocity dispersion curves. As the results, finite amplitude Rayleigh wave propagation is identified. Using the finite amplitude Rayleigh wave, increase in 6 dB of the second harmonic components generated from a closed crack in the glass plate is observed. Rapid increase of the second harmonic component at the condition that width of closed crack, less than 2 nm, is equal to the vibration amplitude of Rayleigh wave is also found out. Potential of closed crack detection is clarified by the use of finite amplitude guided wave system.","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本素材物性学会"}]},"item_10001_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AN10140273","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09199853","subitem_source_identifier_type":"ISSN"}]},"item_10001_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"今野, 和彦"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"武藤, 梓"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Imano, Kazuhiko","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Muto, Azusa","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-16"}],"displaytype":"detail","filename":"sozai20-1c.pdf","filesize":[{"value":"865.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"sozai20-1c.pdf","url":"https://air.repo.nii.ac.jp/record/842/files/sozai20-1c.pdf"},"version_id":"48a561c0-3a63-4981-b31b-f256134e5847"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Air－coupled　Ultrasonic　wave","subitem_subject_scheme":"Other"},{"subitem_subject":"closed　clack","subitem_subject_scheme":"Other"},{"subitem_subject":"second　harmonic　wave","subitem_subject_scheme":"Other"},{"subitem_subject":"finite　amplitude ultrasonic wave","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":"有限振幅超音波を用いた閉ロクラックからの２次高調波の検出","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"有限振幅超音波を用いた閉ロクラックからの２次高調波の検出"}]},"item_type_id":"10001","owner":"3","path":["670"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-03-06"},"publish_date":"2008-03-06","publish_status":"0","recid":"842","relation_version_is_last":true,"title":["有限振幅超音波を用いた閉ロクラックからの２次高調波の検出"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-25T12:00:36.160131+00:00"}
