Theoretical Analysis of Fracture Criterion for Stainless Steel Pipe with Circumferential Through-Wall Crack
The fracture criterion for nuclear reactor stainless steel piping was estimated using simplified methods. This estimation showed that the J-integral fracture criterion (the tearing modulus criterion) and the plastic collapse criterion were established almost simultaneously, and this confirmed the validity of conventional fracture criterion evaluation using the plastic collapse concept.
