Behavior of High-Strength and Ultrahigh-Performance Concrete Targets Subjected to Relatively Rigid Projectile Impact

This experimental study was conducted to evaluate the impact behavior of relatively rigid projectiles with conical and hemispherical nose shapes on normal to high-strength and ultrahigh performance concrete (UHPC). For this impact experiment, target specimens with dimensions of 200×200×100 mm and concrete compressive strengths of 35, 80, 100, 120, and 150 MPa were used. The test results showed that as the concrete strength increased, the...
