Abstract

The terrorist attacks have been increased during the last few years. Blast wave propagation is a great engineering challenge to protect structures such as vehicles and buildings. Mitigation systems used to protect the structures remain a sophisticated engineering problem.
In this study, the V-shape composite structure is studied as a mitigation system to protect the bottom of vehicles against blast impact. The reviewed field blast test is used from another research conducted by Mazek et al.[1] to verify the proposed numerical model of the V-shape composite structures under blast effect. The numerical model is proposed by 3-D nonlinear finite element model (FEM).
The displacement-time history of the V-shape composite (VSC) structure is presented as the blast wave propagates. The impact of the V-shape panel inclination on the V-shape composite structure performance is analyzed and presented under the blast effect. There is a good agreement between the results obtained by both the field blast test and the numerical model. The VCS structure improves the armored panel performance under the vehicles based on the impact of detonating different TNT explosive charges.
