A possible alternative approach is delaying \ufb02utter and alleviating gust response by embedding dissipative materials in structural components. This approach requires accurate damping models applicable to analyze complex con\ufb01gurations. This paper compares three damping models suitable for \ufb01nite element aeroelastic analysis: the viscous model, the hysteretic model, and a generalized Biot model previously proposed by the authors. The damping models are applied to the \ufb02utter suppression and gust load alleviation of a practical aeroelastic testbed using dissipative skin patches. Results obtained using different damping models are compared to provide modeling recommendations for passive \ufb02utter suppression and gust alleviation studies.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2025\/02\/IFASD-2019-085.pdf\">Read the full paper here<\/a><\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Marco Eugeni, Francesco Saltari, Franco Mastroddi, Cristina Riso<\/b><\/p>\n<p>DOI Number: N\/A<\/p>\n<p>Conference number: IFASD-2019-085<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[2440,2433],"tags":[2924,2923,2925],"class_list":["post-18940","post","type-post","status-publish","format-standard","hentry","category-computational-flutter","category-1-ifasd-2019","tag-damping-modeling","tag-passive-utter-suppression","tag-viscoelastic-materials","category-2440","category-2433","description-off"],"_links":{"self":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/18940","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/comments?post=18940"}],"version-history":[{"count":1,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/18940\/revisions"}],"predecessor-version":[{"id":18943,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/18940\/revisions\/18943"}],"wp:attachment":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/media?parent=18940"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/categories?post=18940"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/tags?post=18940"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
