Terrorism has become a major challenge for the world. Terrorist organizations have raised their activities and their attacks in recent years using explosives. These attacks have left numerous numbers of victims, wreaked massive havoc on basic infrastructure, and increased global concern about the nature of these attacks. Blast wall protection systems can provide a required safety level to reduce injuries/casualties in different attack scenarios. Furthermore, installation and procurement costs could be greatly reduced using readily available materials.

Explosions can result from several instances, including but not limited to industrial accidents or terrorist operations. The former can be controlled by considering industrial safety requirements while the latter is far more challenging to maintain. Blind terror does not distinguish between a child, a woman, or an old man. All these are targets for terrorists. Attacks of this nature inside cities targeting civilians and infrastructure have been on the rise in recent years, leaving a massive number of victims in addition to billions of dollars worth of losses. Lately, terrorists have been using innovative and dynamic attack plans to overcome security precautions and surprise security forces. Hence, these attacks have become more complicated to prevent or delay in most scenarios.

While protecting structures from blast loading is important, it is clear that terrorist organizations have been focusing on targeting civilians in open urban settings to produce mass casualties. This trend can be attributed to accessibility to the crowds in open spaces and, in some cases, the inability of the structure to resist abnormal loads. This tutorial investigates the possibility of using readily available (low-tech) materials to develop simple blast wall systems to help mitigate damage from explosives.

The wood cover is modeled as a 3D shell part with fully damaged behavior. During the blast analysis, the wood cover experienced damage and failure because of the severe pressure.

This example is close to the paper here: Probabilistic analysis of a simple composite blast protection wall system
