Research Progress in Penetration/perforation into Reinforced Concrete Targets

The research on penetration and perforation into reinforced concrete targets can provide the necessary support for effective damage effect of earth penetrating weapons and effective protection capability of reinforced concrete structures. The advances in this field are reviewed from the aspects of experimental research, empirical and semi-empirical formula, theoretical modeling and numerical simulation. The typical experimental phenomena of the contrast experiments of plain and reinforced concrete targets and the non-normal penetration experiments of reinforced concrete targets are summarized, the empirical and semi-empirical formulas for calculating penetration depths, residual velocities, etc. are collected, the main research achievements on penetration and perforation into reinforced concrete targets, which include cavity expansion theories, equivalent layered methods, approaches considering the direct impact of reinforcements, etc. are concluded, and the numerical simulations on penetration and perforation into reinforced concrete targets using different numerical methods, modeling approaches, material models are summed up. The research status is evaluated, the experiments and theoretical models are discussed and analyzed, and the potential research directions are also predicted.
