Abstract: The temperature of specimens during the fracture toughness testing, varies due to the heat generation associated with a plastic flow near the crack tip. The temperature has been analyzed using a simple heat balance model and the generated heat has been calculated. Heat generation rate changes in a clear slope corresponding to the stable crack initiation. Hence, this phenomenon can be used for detecting the stable crack initiation. J-integrals were estimated based on the heat variation for three kinds of steels and were found to be close to the ones evaluated by the R curve method.
