The SINTEF/TWI tubular joint tests were analyzed by fracture mechanics methods. Two methods of analysis were employed, 3D shell analysis with Y compliance calibration based on line spring model computations, and a simplified two-dimensional analysis with a load shedding model. The two methods gave results in good agreement with the experimental data. The analyses showed that the fatigue life of tubular joints is not dependent on the hot spot stress alone, but is also significantly influenced by the through thickness distribution of stress, modeled by a degree of bending parameter. For joints with a low degree of bending, standard hot spot stress analysis may be unconservative.
