• 論文の詳細を見る

• In order to determine the strength of structures which are required to be leak-tight, when struck by projectile, a series of impact tests for steel plates have been carried out, and an evaluation formula to estimate the critical fracture energy of SGV49 steel plate for SUS304 projectile has been derived so far. In this study, a series of additional tests for steel plates and projectiles of different material were carried out to investigate the effect of each material on the critical fracture energy. As the result, a new evaluation formula which is applicable to other target and projectile materials was derived.
