Abstract: (298 Views)

One of the important issues in passive defense is creating the maximum attenuation of the blast wave. For this purpose, the current study focuses on reducing the shock wave using zigzag structures. The purpose of this strategy is to produce reflections and refraction of shock waves by using minimal obstruction along the tunnel, unlike the barrier approach. In this research, the amount of attenuation of the shock wave from the center of a tunnel with zigzag wall with 16 different zigzag cases and also one case without zigzag has been investigated. Numerical methods can predict the behavior of materials with appropriate accuracy and away from the limitations of experimental tests. From the numerical simulations, it can be seen that among the various designs of the zigzag structure, the maximum attenuation of the shock wave will be 79.74% at a distance of 19.5 meters from the explosion by a zigzag structure with a height and triangle base equal to 1 meter. In this zigzag design, the initial shock wave undergoes reflection and refraction, which alternately reflects from one side to the other. This rotating and repetitive shock wave reflection helps to spread the shock wave energy without any blockage in the tunnel.
