SUMMARY:Coupled free vibration of liquid in tanks with membrane/ice covers

DESCRIPTION:The talk will focus on the coupled motion of the sloshing of l
 iquid in a tank and the vibration of its elastic cover\, such as a membran
 e or ice/plate cover. In particular\, the circular cylindrical and cubic t
 anks have been considered. Semi-analytical schemes have been developed for
  solving the Laplace equation with boundary conditions with high order der
 ivatives\, which has posed a major challenge to the problem. Equations for
  the natural frequencies of the coupling system are obtained. Detailed inv
 estigation of the corresponding natural mode shapes and principal strains 
 of the cover has been undertaken\, which provides insight into the physic 
 features in the coupled motion. The obtained results can be used for the a
 pplications of seiches in cold regions\, and tuned liquid dampers (TLD) in
  civil and marine engineering.
