The article is focused on materials and their configurations to provide protection against explosive blasts of lightly armored vehicles. The authors consider elastomeric material, aluminum and polyurethane foams which are easily available on the local market at a reasonable cost. A computer simulation method was chosen to solve the problem in an efficient way. The Finite Element Method (FEM) implemented in the LS-DYNA commercial code was used with an explicit (central difference) time integration algorithm. Space discretization for each option was made with three dimensional elements ensuring satisfying accuracy of the calculations. The obtained results indicate that the discussed ballistic panels may be utilized as vehicle crew protection. The investigation proves that panels made of energy consuming materials limit the maximum level of reaction force. The highest reaction is observed when polyurethane foam interacts with a blast wave. In other variants both the forces maximum values and curve shapes are similar. Simulations show that ballistic panel supports rebounds from the massive block quickly after the blast reaches its target, which is crucial for the obtained results.
