The experiment was conducted in a shock tube by measuring pressure along the PU(R) foam in a shock tube, by means of holographic interferometry and streak camera recording. It was found that the stress-strain curve of PU(R) has an inflection point. When the pressure behind the incident shock wave was below the inflection-point pressure P_c, the wave impedance ratio of the incident shock wave and transmitted pressure wave Z_i/Z_t increased sharply. This indicates that only a small amount of energy is transmitted into the foam if the pressure is below P_c. For pressures larger than P_c, Z_i/Z_t decreases asymptotically to a small finite value.","subitem_description_type":"Other"}]},"item_16_publisher_14":{"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":"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/110002976723/","subitem_relation_type_select":"URI"}}]},"item_16_rights_18":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"社団法人日本機械学会"},{"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_16_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1340-8054","subitem_source_identifier_type":"ISSN"}]},"item_16_text_4":{"attribute_name":"著者(機関)","attribute_value_mlt":[{"subitem_text_value":"Department of Mechanical Engineering, Iwate University"},{"subitem_text_value":"Institute of Fluid Science, Tohoku University"}]},"item_16_version_type_27":{"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":"ONODERA, Hideki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TAKAYAMA, Kazuyoshi"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-11-14"}],"displaytype":"detail","filename":"jsmeb-v37-bn2p268-274.pdf","filesize":[{"value":"667.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"jsmeb-v37-bn2p268-274.pdf","url":"https://iwate-u.repo.nii.ac.jp/record/9887/files/jsmeb-v37-bn2p268-274.pdf"},"version_id":"ca8e9f73-cd26-4c0d-986e-f98fdd4e843e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Polyurethane Foam","subitem_subject_scheme":"Other"},{"subitem_subject":"Compressive Wave","subitem_subject_scheme":"Other"},{"subitem_subject":"Wave Impedance","subitem_subject_scheme":"Other"},{"subitem_subject":"Retrograde Material","subitem_subject_scheme":"Other"},{"subitem_subject":"Dispersive Wave","subitem_subject_scheme":"Other"}]},"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":"Shock Wave Structure in Polyurethane Foam","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Shock Wave Structure in Polyurethane Foam"}]},"item_type_id":"16","owner":"3","path":["1519"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-11-30"},"publish_date":"2009-11-30","publish_status":"0","recid":"9887","relation_version_is_last":true,"title":["Shock Wave Structure in Polyurethane Foam"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T11:53:52.334740+00:00"}
