Abstract
The results of numerical modeling of the interaction between a cylindrical titanium impactor and heavy reinforced concrete barriers with steel rebars, using their different mutual positions (configurations) and a number of rebar diameters, are presented. The numerical simulations are performed using the finite element method in a three-dimensional formulation with the EFES software package developed by the authors. The Johnson-Holmquist model, which accounts for plasticity, crack development, and damage accumulation in the material, is used to describe the reinforced concrete destruction. The influence of the reinforcement geometry and configuration on the barrier destruction behavior, the extent of damage, and the impactor residual velocity is examined. These results can be used to optimize the design of protective structures made of heavy reinforced concrete.
