Abaqus tutorials Abaqus simulation and modeling
Simulation of a simple composite blast protection wall system(Wood-Soil) in Abaqus has been studied in this tutorial. The wood panel is modeled as a multi-layer shell part. The soil is modeled as a solid part. You can see a figure of the assembled parts below
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
Dynamic explicit step with CONWEP air blast method is selected. Proper material, boundaries, and meshes are assigned to the parts
After the simulation, all results such as stress, strain, damage, failure, force-displacement diagram, and other important outputs are available. You can see some figures for the results below
