Dynamic analysis of the large strain deformation of flexible pipes conveying two-phase fluids. Part II: nonlinear vibration analysis

This work presents the nonlinear analysis of dynamics large strain deformation subsea flowlines and jumpers conveying two-phase fluid. Precisely, flexible pipes operating in stated condition undergo deformations. Thus, known deterministic model system is solved using method discretized perturbation. this study obtained natural frequency simply supported modelled theory. Results show that both hardening softening behaviors are indicated for pipe undergoing compared with deformations small operational insights parameters sustainable management deformed flow lines two phase made available.
