Abstract
This paper presents the influence of fluid transportation on dynamic properties of three-dimensional extensible marine riser. The interaction between the transported fluid inside the extensible riser and the riser itself is thoroughly addressed. The large strain model formulation of the extensible marine riser is developed by variational approach based on the extensible elastica theory and the work-energy principle. Consequently, the riser also can experience the high extensibility, flexibility, and large displacement conditions. The finite element method based on the updated Lagrangian description is used to obtain the solutions. The numerical examples are given to demonstrate an interesting effect of fluid transportation on dynamic properties of the three-dimensional extensible marine riser.
