Mode coupling internal resonance characteristics of submerged floating tunnel tether

Article Highlights When the tether is only subjected to in-plane or out of plane harmonic loads, if the first-order in-plane and out of plane frequencies of tether are close to each other, the tether is prone to occur modal coupling internal resonance. Since the frequencies of in-plane and out-of-pl...
