要約

The stress−strain state 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 the mechanics of continuous media for an elastoplastic model of a solid with allowance for fracture and a hydrodynamic water model. Depending on the projectile speed, different stress−strain state regimes are observed: from little deformed one at a speed of about 1 km/s to a fractured one at a speed of about 2 km/s. The calculation technique allows the distances in water to be determined at which a metal barrier can be punched in the inertial model.
