Using the weight function method,the fracture of the submarine pipeline with axial surface cracks is studied.Then a practical formula for evaluating the stress intensity factors is derived,which is important and useful in ocean engineering.Based on the solutions of stress intensity factors and statistical models of uncertainties,a reliability assessment methodology on submarine pipelines with surface cracks is proposed,and a computational formula to predict the probability of fracture is given… CONTINUE READING
