Experimental methods play an essential role in developing new designs or materials, but their applications are demanding
in terms of time, cost and realization. Due to the development of knowledge in the field of phenomenological
material models and methods themselves, especially numerical analysis methods of mechanical systems, the design
process and structure analysis is commonly supported by their usage. As far as conventional construction is concerned,
numerical analysis is used routinely in cases when it is necessary to assess the stiffness, durability, frequency
characteristics, etc. But also for example in the analysis of breakdown situations or structures that perform their functions
through a partial or total destruction, as in our case, the development of ballistic shields protection. It is desirable
to carry out experiments and numerical simulations together. We expect a deepening understanding of experiments
due to numerical simulations and also a continuous consequent promotion of rationally designed experiments, thus
reducing their number.
