The present study was carried out to give a physical interpretation to the absorbed energy in Charpy impact test for specimens with mechanical heterogeneity. Standard Charpy impact tests were conducted on several kinds of structural steel with weld bead made by electron beam welding. The results obtained were as follows: (1) It became clear that a large fraction of the absorbed energy in Charpy impact test was associated with the plastic-strain energy consumed to deform a specimen. (2) The absorbed energy of a specimen with mechanical heterogeneity in Charpy impact test was affected not only by the mechanical properties of material under the notch root but also by the mechanical heterogeneity of weld bead in the vicinity of notch. (3) The relation between the absorbed energy and test temperature was determined quantitatively as a function of mechanical properties and constraint distance. キー ・ワー ド:シ ャル ピー衝撃試験,吸 収エ ネルギ,材 質的不連続,溶 接部,塑 性ひずみ エネルギ
