Abstract

In this work, analytical estimation procedures for the evaluation of the crack driving force under strain control for surface cracked pipelines have been examined. Pipes with outer diameter in the range from 10.75″ to 18″ (approx. 0.25 m to 0.5 m) and corresponding minimum wall thickness have been considered. For an assumed level of critical toughness and a range of crack lengths from 25 mm to 200 mm, the maximum acceptable crack depths have been determined for each pipe size. The crack driving forces from different estimation schemes have been compared with the results of a finite-element analysis.
