Abstract:

Five methods are used to calculate plane strain fracture toughness K sub Q values for bend-specimens of various sizes from two high-strength steels. None of the methods appeared to satisfactorily predict valid stress intensity factor K sub IC values from specimens of sizes well below that required by E399 standard tests.
