Unlike linear systems, nonlinear systems can exhibit different types of resonances including fundamental, superharmonic, superharmonic, internal and isolated resonances. In this presentation, we will show how nonlinear modal analysis, and, specifically, the numerical computation of nonlinear normal modes, can be exploited for uncovering and understanding nonlinear resonances. The experimental identification of nonlinear normal modes will also be addressed in the talk.<\/p>\n<p>Speaker\u2019s Biosketch:<\/p>\n<p>Ga\u00ebtan Kerschen completed his Ph.D. degree in Aerospace Engineering from the University of Li\u00e8ge in Belgium in 2003. In 2003 and 2004, he was a visiting postdoctoral fellow at National Technical University of Athens and at the University of Illinois at Urbana-Champaign. Since 2007, he has been a faculty member at the University of Li\u00e8ge, where he is a professor in the Department of Aerospace and Mechanical Engineering. His expertise is primarily in the area of structural dynamics and orbital mechanics. He is the recipient of several international awards including two European Research Council (ERC) grants, the Doak Award from the Journal of Sound and Vibration and the SAGE Publishing Young Engineer Award. He was one of the principal investigators of the OUFTI-1 nanosatellite launched by the Soyuz rocket in 2016. He is the co-founder of NOLISYS, a startup company which provides solutions and software for nonlinear vibrating systems.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Mercoled\u00ec 29 Giugno si svolger\u00e0 presso l\u2019aula Castigliano, un seminario dal titolo \u201cResonances of Nonlinear Mechanical Systems: a Nonlinear Normal Mode Perspective\u201d tenuto dal Prof. Ga\u00ebtan Kerschen, Professore di Ingegneria&#8230;<\/p>\n","protected":false},"author":6,"featured_media":18990,"template":"","meta":{"_acf_changed":false,"inline_featured_image":false,"_price":"","_stock":"","_tribe_ticket_header":"","_tribe_default_ticket_provider":"","_tribe_ticket_capacity":"0","_ticket_start_date":"","_ticket_end_date":"","_tribe_ticket_show_description":"","_tribe_ticket_show_not_going":false,"_tribe_ticket_use_global_stock":"","_tribe_ticket_global_stock_level":"","_global_stock_mode":"","_global_stock_cap":"","_tribe_rsvp_for_event":"","_tribe_ticket_going_count":"","_tribe_ticket_not_going_count":"","_tribe_tickets_list":"[]","_tribe_ticket_has_attendee_info_fields":false,"_tribe_events_status":"","_tribe_events_status_reason":"","footnotes":"","_tec_slr_enabled":"","_tec_slr_layout":""},"tags":[1581,1582],"tribe_events_cat":[930],"class_list":["post-31511","tribe_events","type-tribe_events","status-publish","has-post-thumbnail","hentry","tag-nonlinear-mechanical-systems","tag-nonlinear-normal-mode-perspective","tribe_events_cat-seminari","cat_seminari"],"acf":[],"ticketed":false,"_links":{"self":[{"href":"https:\/\/www.dica.polimi.it\/it\/wp-json\/wp\/v2\/tribe_events\/31511","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.dica.polimi.it\/it\/wp-json\/wp\/v2\/tribe_events"}],"about":[{"href":"https:\/\/www.dica.polimi.it\/it\/wp-json\/wp\/v2\/types\/tribe_events"}],"author":[{"embeddable":true,"href":"https:\/\/www.dica.polimi.it\/it\/wp-json\/wp\/v2\/users\/6"}],"version-history":[{"count":0,"href":"https:\/\/www.dica.polimi.it\/it\/wp-json\/wp\/v2\/tribe_events\/31511\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.dica.polimi.it\/it\/wp-json\/"}],"wp:attachment":[{"href":"https:\/\/www.dica.polimi.it\/it\/wp-json\/wp\/v2\/media?parent=31511"}],"wp:term":[{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.dica.polimi.it\/it\/wp-json\/wp\/v2\/tags?post=31511"},{"taxonomy":"tribe_events_cat","embeddable":true,"href":"https:\/\/www.dica.polimi.it\/it\/wp-json\/wp\/v2\/tribe_events_cat?post=31511"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
