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 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 structure under the blast effect. The numerical model is proposed by 3-D nonlinear finite element model (FEM). The study presents a comparison between the results obtained by both the field blast test and the FEA to validate the accuracy of the 3-D finite element model.
The effects are expressed in terms of displacement-time history of the V-shape composite structure as the explosive wave propagates. The parametric study is also conducted to study the impact of the V-shape panel inclination on the V-shape composite structure performance under the blast effect. The results obtained by the field blast test have a good agreement with those obtained by the numerical model. The V-shape composite structure improves the armored panel performance under the vehicles based on the impact of detonating different TNT explosive charges.
