説明
This study was carried out to characterize the behaviour of brittle fracture initiation at the ductile-to-brittle transition region temperature. In the experiment, V-notch Charpy specimens, which had a local mechanical heterogeneity at the vicinity of the notch root, were used for evaluating the brittle fracture resistance of steel. The absorbed energy of the specimen with mechanical heterogeneity in the Charpy impact test was not a proper measure due to the existence of local mechanical heterogeneity. The elasto-plastic analysis on stress and strain in Charpy specimens with mechanical heterogeneity were conducted by using the finite element method. The energy release rate for crack propagation in Charpy specimens with mechanical heterogeneity was calculated. It was shown that the energy release rate could be employed as the criterion for ductile-to-brittle transition in the Charpy test.
