In this study, burst tests of pipes with local wall thinning under internal pressure were performed, and it was shown that fracture mode of the pipes varies with local wall thinning length. In order to develop a prediction methodology of fracture mode of pipes with local wall thinning, strains in axial and in circumferential direction of the pipe were examined in detail. The examination revealed that the ratio of the strains in axial and in circumferential direction of the pipe could be used as the parameter to predict the fracture mode of pipes with local wall thinning.
