Stability of Deep-Water Pipelines Under Combined Loading
S.A. Karamanos and J.L. Tassoulas, University of Texas at Austin
This work investigates the response of relatively thick inelastic tubes under combined external pressure, bending and tension. A nonlinear finite element analysis technique is adopted. Results are presented in the form of pressure-bending, pressure-tension and tension-bending diagrams and are of direct significance in the design of deep-water pipelines.
