Armoured vehicles usually employ shaped plate for protection from blast loads arising from landmines. In most of the cases the plates deflect a part of the load away from the vehicle thus protecting the crew. Important parameters which affect the design of the plates include the included angle of the V shaped plate and standoff distance between the explosive and plate. In this study Finite Element (FE) analysis is carried out to estimate energy absorbed by the plates and the impulse transmitted to the superstructure. A validated numerical procedure with ABAQUS is used to conduct the parametric studies to compare and estimate the effectiveness of two different configurations. Guidelines for selecting the required plate angle and location of the plate could be developed based on the suggestions of the numerical study.
