The beam is immersed in the fluid\nwhich fills a two-\ndi mensional rectangular domain with periodic boundary conditions in both\ndi rections\,\nwhile both the beam and the fluid are under the effect of time -periodic\nforces. By using\na decoupling approach\, at least one time-per iodic weak solution to this\nproblem is con-\nstructed which has a bounded energy and a fixed prescribed mass. The\nlack of a priori\nenergy bounds is overcome by a series of estimates based on a careful\nchoice of paramet ers.\nThe time-periodic solution is constructed by a series of limit\nproc edures.\nThis is a joint work with V. Mácha\, Š. Nečasová and S. Trifu nović.\n LOCATION:https://researchseminars.org/talk/NSCM/171/ END:VEVENT END:VCALENDAR
