Estimation of the Fracture Resistance Curve for the Nuclear Piping Using the Standard Compact Tension Specimen

Translating the material fracture resistance into representations in welded tubular structures

“…The current study focuses on the data from small-scale yielding, high-constraint fracture specimens, in deriving the lower-bound J-R curve. The J-R curve data included in the current study covers a wide range of structural steels with various grades for different applications, comprising of the pressure and reactor vessel steels [37][38][39][40][41][42], pipe and pipeline steels [43][44][45][46][47][48], steels for other structural applications [49][50][51][52][53][54][55][56][57][58][59][60][61][62][63][64][65] and weld materials [66,67].…”
