    Abstract

    The effects of the striking edge radius of the Charpy impact test on the absorbed energy and lateral expansion were investigated. The effects of the changes of the length of test specimens and effects of symmetry of test specimens was also investigated. The absorbed energy of the 8mmR's was higher than the 2mmR's as in the study by Naniwa et al.[1]. For every machine tested, the absorbed energy was higher when the striking point did not contact the specimen opposite the notch. The effects of the length of test specimens were larger when the asymmetric test specimens were tested.
