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.
