In a full method harmonic analysis, when I introduce a discrete excitation, I mean an excitation of 0,5 mm as amplitude at a specified frequency, for example at 9 Hz (considering that the amplitude value is 0 for the rest of frequencies). If the first natural frequency of my structure appears at 15 Hz, should I ontain any stress or displacement results at the frequency of 9 Hz?<\/span><\/p>\n<p class=\"MsoNormal\"><span>I know that at that frequency I will not have any amplification and the stress or displacement results should keep low. I thought I would obtain any result different to zero, but I did not gat them. So, my question is that if the frequency of my excitation is far from the natural frequencies of the structure, should I get results in a Full Method or in a Modal Superposition Harmonic Analysis?<\/span><\/p>\n<p class=\"MsoNormal\"><span>Thank you very much for your help!<\/span><\/p>\n","protected":false},"template":"","class_list":["post-291298","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["288543","20905","603"],"_bbp_author_ip":["168.143.243.24"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["304"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["291298"],"_bbp_forum_id":["27791"],"_bbp_engagement":["603","20905","288543"],"_bbp_voice_count":["3"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["291686"],"_bbp_last_active_id":["291686"],"_bbp_last_active_time":["2023-07-05 15:06:54"]},"test":"pedro-argoteingeteam-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/291298","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\/291298\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=291298"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
