The tensile strain limit for leak of high pressure pipe with circumferential surface notch is simulated by FE-analysis based on the proposed damage evolution models, and compared with the experimental results. The simulation model for ductile crack growth accompanied by penetration through wall thickness consists of two criteria. One is criterion for ductile crack initiation from the notch-tip, in which plastic strain at notch-tip at onset of ductile cracking can be constant independent of shape and size of components as well as loading mode. The other is damage-based criterion for simulating ductile crack extension associated with damage evolution influenced by plastic strain as well as stress triaxiality ahead of the extended crack-tip. In this report, it is demonstrated that the simulation model can be applicable to predicting ductile crack growth behaviors of a SENT (Single Edge-Notched Tension) specimen and a circumferentially notched pipe with internal high pressure subjected to tensile loading.
