The 19th International Conference will be held from June 29th to July 3rd, 2020, at the National University of Science and Technology "MISIS", Moscow, Russia. The conference is the 19th in a series that began in Providence (USA) in 1956 and continued in Ithaca (USA, 1961), Manchester (England, 1965), Providence (USA, 1969), Aachen (Germany, 1973), Tokyo (Japan, 1977), Lausanne (Switzerland 1981), Urbana (USA, 1985), Beijing (China, 1989), Rome (Italy, 1993), Poiters (France, 1996), Buenos Aires (Argentina, 1999), Bilbao (Spain, 2002), Kyoto (Japan, 2005), Perugia (Italy, 2008), Lausanne (Switzerland 2011), Hefei (China, 2014) and Foz do Iguaçu (Brazil, 2017). The ICIFMS-19 is a great opportunity for the exchange of experiences, innovative ideas, and research focused on theory, advances and applications of internal friction and mechanical spectroscopy, dynamic-mechanical analysis, high and low damping materials and new techniques of internal friction and mechanical spectroscopy. We also encourage and invite scientists from neighboring research fields to share their expertise, which will make ICIFMS-19 an event not to be missed.
