Aluminum foam is a lightweight material with high energy absorption capacity. In this study A Nonlinear three-dimensional hydrocode numerical simulation was carried out using autodyn-3d, which is an extensive code dealing with explosion problems. In this simulation, a high explosive material (comp B) is blasted against several concrete panels. The model was first validated using experimental tests carried out by Chengqing and has shown good results. Several numerical tests were carried out to study two parameters that affect the deflection of reinforced concrete panels. The parameters included are the thickness of concrete target and the thickness of steel plate. The results showed that increasing the thickness of the steel plate has an insignificant effect on the deflection of the reinforced concrete target while increasing the thickness of the concrete panel has a significant effect on the deflection of the concrete target.

The Impact

Data from the Tsubota et al. (1993) experiments provided the basis for a numerical study that investigated the impact response of steel-plate lined, reinforced concrete panels using the SPH formulation in LS-DYNA. The simulated tests involved 50 mm (1.97 in), 70 mm (2.76 in), and 90 mm (3.54 in) thick reinforced concrete (RC) panels with steel liners and one 50-mm thick benchmark RC panel. Three of the five panels had a steel liner attached to the back face and one had a steel liner on both faces. The panels were normally impacted by a 39.6 mm (1.56 in) diameter projectile at a velocity of 170 m/s (6693 in/s). Reasonable predictions of observed damage, including perforation, liner fracture or bulging, and concrete scabbing were achieved using the MAT072R3 concrete material model. The effectiveness of adding steel liners to a concrete panel to prevent perforation and scabbing resulting from projectile impact was investigated using the numerical model and MAT072R3. Installing a steel liner on the back face of a panel, with a reinforcement ratio equal to that of the internal reinforcement, is an effective method to mitigate scabbing but has little effect on perforation resistance.

Aircraft Crash

Due to the rear-face steel plate of the steel plate concrete wall (SC) is very effective in preventing the perforation and scabbing of concrete, in order to resist the impact of commercial aircraft crash, steel plate concrete structures are usually used in the design of external walls of nuclear power plants. In this paper, the simulation analysis of the impact test of 1/7.5 scaled aircraft model impacting the steel plated concrete panels is carried out by using finite element code ANSYS/LS-DYNA. The Winfrith material model (*MAT_84) in ANSYS/LS-DYNA is used to simulate the concrete. The damage profile of panels and residual velocity of aircraft engine comparisons between the simulations and tests are presented in this paper. The results indicate that the damage modes from the impact simulations are very good agreement with the experimental result. It is verified that not only the selection of the material parameters needed for the steel plated concrete wall and aircraft model but also the entire analysis method was appropriate and effective. This paper provided the effective methodology for simulation of the response of the steel plated concrete structure of nuclear power plant due to commercial aircraft crash impact.
