Coupled structural response via fluid medium
MetadataShow full item record
Dynamic loading can be transferred from one structure to another via fluid media with fluid–structure interaction (FSI). Previous studies demonstrated that FSI played a critical role for polymer composite structures in contact with water because their material densities are very comparable to that of water. This paper studied the structural coupling effect through a fluid medium contained among the structures. This study was an extension of the previous experimental work reported in Kwon and Bowling (Multiscale Multidiscip Model Exp Des 1(1):69–82, 2018). Composite structural stiffness, spacing and the number of coupled structures were varied in the experiments to determine their effects. The experimental results showed that the effects of different parameters on the structural responses of couple structures were quite complex, and they have to be well understood for proper design of coupled structures via a fluid medium.
