Experimental and Numerical Study on Strength of Concrete Slabs under High Speed Projectiles

Concrete elements under high-speed projectiles effect has an increasing interest recently. Understanding to what extent the concrete can resists the effect of projectiles, very necessary in design structures in order to save the occupants. The objective of this study is to develop improved num...
