3D FE-simulation of high-velocity fragment perforation of reinforced concrete sl

In a research project, various codes and three-dimensional material models for concrete were used in simulations of some test cases, e.g. impact loads on beams, blast loads from explosives on slabs and projectile perforation through slabs. Numerical results were compared with observations in tests and reported. In this paper, simulations using LS-DYNA (LSTC, Livermore, June 1997) for the projectile perforation of a 60 mm thick "bre-reinforced concrete slab with a velocity of 1500 m/s is presented.
