Calculation of resistant of new barrier against track weighting 7.5 tons at 80 kilometers per hour was made. The calculation made using ANSYS-LSDYNA. At first only the barrier and the track were modelled. The simulation made using Lagrange method. Multiple contacts (Lagrange-Lagrange interaction) inserted between the barrier and the track parts. Enhancements were added to the barrier due the simulation. At second stage reinforced concrete was added. The concrete modeled using Euler method and the reinforcement modelled using Lagrange method. FSI coupling (Euler-Lagrange interaction) made between the Euler concrete and the reinforcement and the barrier. At third stage a sand was added to the model. During the simulation the concrete disconnects from the sand but the barrier does not fall over. The resulting plastic strain in the barrier was local and tiny so there will not be a development of fracture due the impact. Stress above yield point was for a short duration and wasn’t cause of fractures in the barrier.
Two months after making the simulation experiments were done in the United States for the purpose of obtaining approval for the sale of the barrier. The experiments were consistent with the simulation results.
