Assessment of the fracture toughness of cast steels

Part 1 Low alloy steels
  • J. T. Barnby

Estimates of the fracture toughness in terms of the critical stress intensity factorsKC andKIC are made for a 1Cr steel, a 1/2Cr-1/2Mo-1/4V steel, a 1 1/2Mn-Ni-Cr-Mo steel and a 1 1/2 Ni-Cr-Mo steel all in cast form. The methods used are linear elastic fracture mechanics,J-integral and crack opening displacement methods. The last two methods are applied in combination with an electrical potential method to detect the initiation of fracture.
