Shaped plates assume importance in the design of armoured personal vehicles (APV). These plates are used as blast mitigation structures against land mine blasts. These shaped plates deflect and absorb a certain part of the energy imparted to them. The blast mitigating capacity at a particular impulse level mainly depends on material and the geometric parameters of the plate under consideration. The objective of this paper is to conduct a finite element (FE) based failure analysis and parametric study on the blast mitigating capability of steel plates. The important parameters of interest are the mass of the explosive and the included angle of the V shaped plate. A numerical study on V-shaped plates is carried out with ABAQUS to predict the midpoint deflection and impulse transmitted. The verified simulation procedure is repeated for conducting the parametric study. The study may be used in setting up guide lines for the design of V shaped plates for protecting vehicles.
