Lock-in of the vortex-induced vibrations of a long tensioned beam in shear flow [PDF]
, 2011 The occurrence of lock-in, defined as the local synchronization between the vortex shedding frequency and the cross-flow structural vibration frequency, is investigated in the case of a tensioned beam of length to diameter ratio 200, free to move in both
