KIC SIZE EFFECT STUDY ON TWO HIGH-STRENGTH STEELS USING NOTCHED BEND SPECIMENS

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.
