Dynamic analysis and design of V-shape plates under blast loading

Since World War II, more vehicles have been lost to land mines than all other threats combined. Anti-vehicular (AV) mines are capable of disabling a heavy vehicle, or completely destroying a lighter vehicle. The most common form of AV mine is the blast mine, which uses a large amount of explosive to directly damage the target. Nowadays, V-shape hulls are widely used in armored demining vehicles to reduce the effects of mine blast. This paper presents the comparative results of dynamic analysis of the response of V-shape plate subjected to mine blast load using finite element analysis package ABAQUS. Various layers of materials like metals, lightweight foams and Balsa wood are used inside the V-shape plate to analyze their effects on the deformation of the plate and applied stresses and strains. The results indicate that application of aluminum and aluminum-foam leads to considerable reduction in deformation of the plate and consequently results in more energy dissipation and enhances crew survivability. © VIBROENGINEERING.
