Simulation of pressures behind rigid blast walls

This work presents numerical studies for predicting the protection to buildings provided by blast walls (sometime called `blast barriers'). The blast walls are assumed to be non-deformable. Simulations are done by using the Arbitrary Lagrangian Eulerian (ALE) technique of the commercial finite element code LS-Dyna. The effects of the blast wall height and the stand-off distance of the building behind the blast wall in reducing the overpressure of the blast wave are investigated.
