In order to clarify the strength of structures which require leak tightness, when struck by projectiles, a series of impact tests for steel plates have been carried out. Cylindrical, semi-spherical and conical-nosed SUS304 stainless steel projectiles were impacted onto carbon steel target plates 7〜38 mm thick. Test results showed that critical fracture energies of target plate by cylindrical and semi-spherical -nosed projectiles mostly agree with the values predicted by empirical formulas generally used, however, the critical fracture energy of target plate by a conical-nosed projectile is fairly smaller than these values. An evaluation formula for the critical fracture energy of target plate, applicable to three kinds of nose shaped projectiles, has been derived from the test results.
