บทคัดย่อ

This paper presents the effect of axial extensibility on three-dimensional behavior of the tensioned pipes/risers. The large strain model formulation is developed by variational approach based on the elastica theory and the work-energy principle. The finite element method is used to find the nonlinear static configuration and large static strain. The natural frequencies and mode shapes are calculated by using the assumed-modes finite element method. The pipes/risers perform tensioned beam behavior when the bending stiffness dominates, and the stability of the pipes/risers reduces as the axial extensibility increases. On the contrary, the pipes/risers perform the tensioned cable behavior when the axial stiffness dominates, and the stability of the pipes/risers increases as the axial extensibility increases.
