摘要：
The elastic-plastic fracture of carbon steel piping having various pipe diameter and circumferential crack angle subjected to the bending moment was analyzed using the latest CEGB R6 approach (R6 method) and ASME Screening Criteria (SC method). It is required to apply the elastic-plastic fracture criterion instead of the plastic collapse criterion with increase of the pipe diameter and the crack angle. The SC method gives a more conservative estimation than the R6 method. A simplified elastic-plastic fracture analysis procedure based on the R6 method is proposed.
