The main focus was applied to absorbing capability of the multilayer sandwich. Results from numerical simulations were compared with experimental tests. The test procedure is provided according to STANAG 4569/AEP-55 standard with threat level 3B. The main armor material, aluminum, enables high local plastic deformation and high global deflection of the plate. The aluminum foam layer increase an absorption capacity of the armor assembly against a surface attacks. The material crushable foam was used for the aluminum foam layer modeling. Soil, air and explosive were modeled using Euler type FEM grids. Not only deflection, but also stress and strain values were evaluated over all multilayer plates. The residual deflection presents good correlation between the simulation and test. The main goal of this project was to develop a multilayer armor that is able to protect a typical military vehicle against the 8 kg TNT blast mine. It was achieved by a combination of an aluminum base armor, aluminum foam, a glass fiber laminate and ballistic steel sheet.
