This paper presents a numerical approach to predict failure in the reinforced V-shape plates subjected to blast loading. V-shape plates are commonly used in the vehicle’s hull to mitigate the blast pressure effects. In the current research, V-shape plates were reinforced using multi-arch surfaces and honeycomb energy absorbers. Ductile and shear damage parameters were introduced to simulate failure in the finite elements models. Results of this study show that applying V-shape plates along with reinforcing elements significantly enhance the energy dissipating capacity of the V-shape hulls without overloading the vehicle. Also, based on the numerical calculations, upward reaction force was reduced by five times in the reinforced V-shape plate compared to the simple V-shape plate. Finally, it was shown that weight reduction by 2.5 times is achieved by the reinforcing V-shape plates in comparison to flat plates imposed to 50 g TNT explosive.
