Abstract:

Constitutive modeling of the NANOS-BA® steel is described in this article. Results of the experiments (quasi-static uniaxial tension and uniaxial compression, high strain rate compression with use of the Split Hopkinson Pressure Bar) are shown. On the basis of the experiments results, the values of constants of the Johnson–Cook (J–C) model for the NANOS-BA® steel were determined. Verification of the determined values of constants was described, in which the stresses and strains obtained in samples in experiments and simulations were compared. The additional verification of the determined parameter values was the comparison of the depth of penetration tests (DP tests) results of NANOS-BA® steel plates placed on the Armox 500T „witness” plate fired with a 12.7 mm B-32 projectile, obtained experimentally and in simulations. Small differences between simulation and the experiments results testify that the determined values of constants of J–C model for NANOS-BA® steel provide good agreement with experiments.
