Abstract
Impact compression experiments were carried out for steel specimens of which length were 20, 40 and 60 mm at 18, -72 and -185°C, respectively. The size of plastic region produced in a specimen by an impact compression depends on the length of specimen, which was longer for bottom end than that of upper impact end. These results were discussed based on the superposition of stress waves. When an impact compression was imposed on a specimen superposed on a static compression, equivalencies between the static stressσs andσ^^·d which was stress gradient of a stress wave. Swelling over the plastic region observed by an interferometer corresponded to the consideration on the dynamic stress state in specimen. Distributions of hardness along the length of specimen were also studied.
