Both effective density and bulk modulus have complex quantities to represent damped sound fields in the porous media. Particle displacements in the media are discretised using finite element method. For solid body, displacements are modeled using conventional finite elements including complex modulus of elasticity. Displacement vectors at common unknown varriables, are solved under coupled condition between solid body, porous media and air. Further, explicit expressions of modal loss factor for the mixed structures are derived using asymptotic method. The proposed methods yield appropriate results for some sample problems. Moreover, it is found that damping can be coupled in the mixed structures.","subitem_description_type":"Abstract"}]},"item_6_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本機械学会"}]},"item_6_relation_43":{"attribute_name":"異版である","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":" http://ci.nii.ac.jp/naid/110002378822/","subitem_relation_type_select":"URI"}}]},"item_6_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"日本機械学会"},{"subitem_rights":"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"}]},"item_6_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0387-5024","subitem_source_identifier_type":"ISSN"}]},"item_6_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00187463","subitem_source_identifier_type":"NCID"}]},"item_6_version_type_15":{"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":"山口, 誉夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"黒沢, 良夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"松村, 修二"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-11-25"}],"displaytype":"detail","filename":"C69_34.pdf","filesize":[{"value":"758.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"C69_34.pdf","url":"https://gunma-u.repo.nii.ac.jp/record/3458/files/C69_34.pdf"},"version_id":"2f49ba28-0327-4b55-ad92-1693d81564cd"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Damping","subitem_subject_scheme":"Other"},{"subitem_subject":"Damping Material","subitem_subject_scheme":"Other"},{"subitem_subject":"Sound-Proof Structure","subitem_subject_scheme":"Other"},{"subitem_subject":"Computer Aided Analysis","subitem_subject_scheme":"Other"},{"subitem_subject":"Porous Media","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":"固体-多孔体-空気からなる防音構造の減衰特性のFEM解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"固体-多孔体-空気からなる防音構造の減衰特性のFEM解析"},{"subitem_title":"Finite Element Analysis for Damping Properties of Sound-Proof Structures Having Solid Body, Porous Media and Air","subitem_title_language":"en"}]},"item_type_id":"6","owner":"2","path":["576"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-02-05"},"publish_date":"2008-02-05","publish_status":"0","recid":"3458","relation_version_is_last":true,"title":["固体-多孔体-空気からなる防音構造の減衰特性のFEM解析"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-06-19T13:00:45.690913+00:00"}
