In order to evaluate the integrity of the cracked pipes for general case, a limit load estimation method has been proposed by authors considering a circumferential surface crack with arbitrary shape. In this paper, the proposed method was verified by comparing with experimental results. Four-point bending experiments were carried out for full scale stainless steel pipes with a symmetrical or asymmetrical circumferential crack. Estimated failure bending moments by the proposed method were found to be in good agreement with the experimental results, and the proposed method was confirmed to be effective for evaluating bending failure of pipes with crack.
