| Abstract: | In this paper the true stress-strain curves of carbon steel pipes are described by a three-segment fitting method rather than the Ramberg-Osgood relation for their yield plateau characteristics. Failure assessment curves for carbon steel piping containing circumferential through-wall cracks were obtained by different options in the CEGB/R6 approach. The J-integral was calculated using a new expression proposed by the authors. Initiation and maximum moments of piping under bending were predicted by several methods and measured by experiments. Calculated moments were quite close to test results. |
