Rapid advances in digital signal acquisition and processing are fully utilized to extract ultrasonic features of sound velocity, velocity dispersion, attenuation, attenuation spectrum, and the second harmonic amplitude. The combination of these ultrasonic features with theories developed by physical acoustics provides a quantitative evaluation of characteristics and damage of structural materials. In particular, the effectiveness of non-linear ultrasonics is emphasized. The non-linear ultrasonic method using large incident wave amplitude measures dynamic response at minute cracks or voids. Moreover, this method does not depend on propagation distance, different from sound velocity and attenuation. This opens the possibility of a new non-destructive evaluation of initial structural damage such as fatigue, creep, stress corrosion, radiation damage, etc.","subitem_description_type":"Other"}]},"item_9_description_11":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_9_full_name_4":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"4874","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kawashima, Kouichiro"}]}]},"item_9_link_14":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_link_text":"40006264782","subitem_link_url":"https://ci.nii.ac.jp/naid/40006264782"}]},"item_9_publisher_6":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"名古屋工業大学"}]},"item_9_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0918595X","subitem_source_identifier_type":"ISSN"}]},"item_9_source_id_8":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10389180","subitem_source_identifier_type":"NCID"}]},"item_9_version_type_9":{"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":"川嶋, 紘一郎"},{"creatorName":"カワシマ, コウイチロウ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-02-09"}],"displaytype":"detail","filename":"bnit2004_019.pdf","filesize":[{"value":"2.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"本文_fulltext","url":"https://nitech.repo.nii.ac.jp/record/6185/files/bnit2004_019.pdf"},"version_id":"24ed7676-f8f2-41d1-bb3c-687df6dad03d"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ultrasonic evaluation","subitem_subject_scheme":"Other"},{"subitem_subject":"non-destructive testing","subitem_subject_scheme":"Other"},{"subitem_subject":"non-linear ultrasonics","subitem_subject_scheme":"Other"},{"subitem_subject":"higher harmonics","subitem_subject_scheme":"Other"},{"subitem_subject":"material characterization","subitem_subject_scheme":"Other"},{"subitem_subject":"digital signal processing","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"線形及び非線形デジタル超音波計測による構造材料の非破壊特性評価","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"線形及び非線形デジタル超音波計測による構造材料の非破壊特性評価"}]},"item_type_id":"9","owner":"3","path":["623"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-02-09"},"publish_date":"2018-02-09","publish_status":"0","recid":"6185","relation_version_is_last":true,"title":["線形及び非線形デジタル超音波計測による構造材料の非破壊特性評価"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-05-15T13:50:54.358027+00:00"}
