DOI: 10.1016/j.apor.2019.101856
Abstract: Abstract Vortex-induced vibrations (VIV) of slender marine structures are complicated response processes, where a number of distinct frequency components might be simultaneously active. These are categorized as fundamental and higher harmonics respectively, where the latter… read more here.
