- This paper presents the methods of testing the materials subjected to static and dynamic tensile tests, presented for 10GHMBA - E620 bainitic steel. The tests were conducted on the MTS 810.12 universal strength testing machine, a rotary hammer, a station especially designed for the conditions required for the Taylor test, an equipped ballistic pendulum and high-speed digital camera Phantom v12. The data collected in the tests are necessary for strength calculations of these constructions. The calculations are performed with the use of numerical methods and computing techniques, including constitutive equations for the performance description of a given material. Specific parameters and material constant values for the missile and the shield are accounted for in the equations. The parameters and constant values are either determined in experiments or 'selected', which is a significant issue in the case of high deformation speed. The final section presents examples of numerical simulations which enable the analysis of quick change processes which occur when a construction is subjected to strains due to strike with an object moving at a high speed, such as a 12.7 mm calibre missile moving at approx. 1000 ms-1. The knowledge of mechanical properties of materials is crucial in designing constructions exposed to direct fire and other dynamic effects. The results are presented in the form of charts and graphs.
