The method utilizes simple approximate expressions for determining the fracture parameters K, J, and employs these parameters to determine critical dimensions of a crack on the basis of equality between the J-integral and the J-based fracture toughness of the pipe steel. The crack tip constraint is taken into account by the so-called plastic constraint factor C, by which the uniaxial yield stress in the J-integral equation is multiplied. The results of the prediction of the fracture condition are verified by burst tests on test pipes.}, journal = {International Journal of Mechanical and Mechatronics Engineering}, volume = {5}, number = {1}, year = {2011}, pages = {67 - 74}, ee = {https://publications.waset.org/pdf/10332}, url = {https://publications.waset.org/vol/49}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 49, 2011}, }
