Bio-Inspired of Pyramidical Concrete Barrier Walls against the Effects of Explosion Waves

Abstract

Biomimicry is a technique that inspired solutions to engineering problems through the study of natural systems, designs and processes. Recently, the engineering Biomimicry technique has been used to inspire a protection system against the blast waves and that can mitigate, absorb, and reflect the blast waves. Hence, this work studies the effect of different geometrical configurations of concrete wall barriers inspired by nature against blast waves. The non-linear 3d numerical model is used to model the proposed configurations. The finite element modeling is validated with referenced experimental works. The response of the proposed structural configurations of the wall barrier is analyzed. The results showed that the new bio-inspired pyramidical structure configuration (PCBW) has a notable effect on the mitigation of blast hazards which gave the best performance for the protection of the area behind the wall barrier with 19.5% with respect to traditional concrete barrier wall (TCBW). Also, it is concluded that nature inspiration has a great effect on designing new protection systems against the effect of blast waves.
