Motivated by Godfrey's paper [1], we planned and executed an experimental program to study the perforation of 48 MPa (7 ksi) and 140 MPa (20 ksi) strength concrete slabs. The 48 MPa (7 ksi) concrete is typically used for the construction of structural members, so we obtained ballistic perforation data for typical and high-strength …
