Abstract

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 multiarch 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.
