“…As β decreases, the correlation of vortex shedding along riser span affecting the lock-in regime is expected to increase and eventually become maximized when β = 0 in uniform flow case. Copyright © 2010 by ASME Based on the so-called engineering strain description, the nonlinear extensional dynamic strain e d due to finite-amplitude cross-flow motion of riser is considered and expressed as [15] ( )…”

“…Static analysis of inclined cables is also performed in [5], as a starting point for further studies on the dynamics of cables embedded in quiescent viscous fluids; there, reference to the solution of the static catenary is given to [6]. Free nonlinear dynamics are analyzed under different conditions in [7][8][9], where the static approximate equilibrium configuration is taken from [4]. The dynamics of inclined cables are addressed in [10] in the case of taut conditions, using as a key factor the small sag-to-span ratio.…”

“…Abe [10] investigated the accuracy of nonlinear vibration analyses of a suspended cable, which possesses quadratic and cubic nonlinearities, with 1:1 internal resonance. The nonlinear dynamics of suspend cable structures have been studied with 2:1 internal resonances by the authors [11,12]. Experimental studies of this problem have been conducted by Alaggio and Rega [13] and Rega and Allagio [14], however explicit stability regions for the semi-trivial solution have not been calculated analytically.…”
