| Abstract | This study involves the numerical simulation of crack growth in girth welds of steel catenary risers under constant tension and cyclic bending. The modeling was carried out with the aid of a finite elements framework and a fracture mechanics program, which generates the initial crack and updates the model mesh according to the local energy release rate of the crack front nodes. The non-linear analysis comprises three-dimensional model mesh with solid elements, finite rotations, elastic-plastic behavior of the material and the linear theory of fracture mechanics. The numerical results were qualitatively compared with proposed fatigue curve of the British Standard International code. |
