MODELLING OF THE SIMULATION OF METAL DISC DEFORMATION IN 3D GEOMETRY Radić N.Vlado Momirović Ž.Vladimir The deformation of a real-configuration concave disc in an antitank mine is analyzed. In the DYNA3D software the disc is modelled by three-dimensional finite elements. The deformation of the disc by the influence of detonation products is monitored in time sequences. In the part of software (preprocessor) called IN6RID the input data for the DYNA3D processor is formed and the results are interpreted in the TAURUS program (postprocessor). On the basis of calculations, strain, deformation, maximum pressure and velocites are analyzed in the whole disc.
