For that I thought of doing the harmonic analysis and finding the amplitude response over varied frequency. Then using half power bandwidth method I can get the damping coefficient. I don&#8217;t know if the approach is correct or not, rectify me if wrong. The main problem that I find here is assingning material properties. I assigned density, isotropic elesticity and then prony shear relaxation terms but that is not giving me satisfactory results.&nbsp;&lt;br&gt;If someone know how to assign properties to viscoelastic material please let me know.&nbsp;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-458709","topic","type-topic","status-publish","hentry","topic-tag-add-material","topic-tag-harmonic-analysis","topic-tag-viscoelastic-simulation-2"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27815"],"_bbp_topic_id":["458709"],"_bbp_subscription":["690808","20905"],"_bbp_author_ip":["106.51.68.169"],"_bbp_last_reply_id":["458751"],"_bbp_last_active_id":["458751"],"_bbp_last_active_time":["2026-05-23 15:54:00"],"_bbp_reply_count":["4"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["690808","20905"],"_btv_view_count":["51"],"_bbp_topic_status":["unanswered"]},"test":"me230003066iiti-ac-in"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/458709","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/458709\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=458709"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
