摘要：

The stress-strain state (SSS) of projectiles is investigated when a high-speed projectile enters water and interacts with barriers protected by a water layer. Experimental investigations are carried out using a high-speed ballistic setup. Calculations are performed within the framework of mechanics of continuous media for an elastic plastic model of a solid with allowance for fracture and hydrodynamic water model. Depending on the projectile speed, different SSS regimes are observed: from small deformed at a speed of a parts per thousand 1 km/s to fractured at a speed of a parts per thousand 2 km/s. Calculation technique allows distances in water to be determined at which the metal barrier can be punched for the inertial model.
