Analysis of metal disc effects on armor vehicles and protection possibilities

In this paper the deformation of a concave disc in real configuration in an antitank mine is analyzed al well as its effect on armor vehicles. The disc is modeled by three-dimensional finite elements DYNA3D in the software. The deformation of the disc by the influence of detonation products is monitored in time sequences. In the part of software called INGRID (preprocessor) the input data for the DYNA3D processor is formed and the calculation results are interpreted in the TAURUS program (postprocessor). Based on calculations strain, deformation, maximum pressures and velocities are analyzed in the whole disc.
