Numerical explicit analysis of absorbing materials used in multilayer mine protection

Popis výsledku v původním jazyce

An interaction of the blast pressure wave after detonation of a blast mine under the multilayer mine protection mounted on a military vehicle is described in this project. 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 globaldeflection 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 Eulertype 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 dev
