摘要：

This paper is concerned with the creep analysis of pressurised pipe bends in which ovality of the circular cross-section is considered. A creep continuum damage mechanics analysis is performed using the Finite Element method. The failure times and failure positions are predicted and compared to steady-state creep solutions. A comparison of the two solutions shows that the steady-state creep solutions for failure times are conservative compared to the damage solutions.
