ASTM Standard Test Method E 1820-96, “Measurement of Fracture Toughness,” was recently revised (E 1820-98). This revision includes a relaxation of the deformation limits/size requirements that must be satisfied to report a valid value of fracture toughness at instability prior to significant stable crack extension (JC). E 1820-96 required that valid JC values satisfy the following inequality (with an M value of 200).
fracture toughness testing, cleavage fracture toughness, deformation limits, size requirements, JC, constraint, ferritic steels
