Ballistic impact on concrete slabs: An experimental and numerical study

Ballistic impact on concrete slabs: An experimental and numerical study

The ballistic perforation resistance of 50 mm thick concrete slabs impacted by 20 mm diameter ogive-nose steel projectiles is investigated experimentally and numerically. Three commercially produced concretes with nominal unconfined compressive strengths of 35, 75 and 110 MPa were used to cast mater...
