Constraint Assessment for Cruciform Specimens With a Semi-Elliptical Crack [PDF]
Volume 6A: Materials and Fabrication, 2018 A real crack to be assessed in a RPV is generally a shallow crack subjected to biaxial far-field stresses. However, the fracture toughness Kc or Jc, which is an important material property for the structural integrity assessment of RPV containing cracks, are usually tested on deep cracked compact tension [C(T)] or single-edged bending [SE(B)] specimens

High-resolution 3D weld toe stress analysis and ACPD method for weld toe fatigue crack initiation [PDF]
, 2019 Weld toe fatigue crack initiation is highly dependent on the local weld toe stress-concentrating geometry including any inherent flaws. These flaws are responsible for premature fatigue crack initiation (FCI) and must be minimised to maximise the fatigue
