We have performed finite element calculation of precracked Charpy-like three-point bending specimen, in order to analyze the effect of warm prestressing on fracture toughness value of reactor pressure vessel steels. Two different hardening laws were applied in the calculation. J-integral was determined in both cases and comparative analysis was made.
