General assumptions of educational faculties at universities are specified by the instructions of the Polish Ministry of Science and Higher Education.
Instructions concerning educational directions at universities have been specified in the ordinance issued by the Ministry of Science and Higher Education and published in the Polish Journal of Laws [4].
A student commencing the design classes should have credits in the basic subjects, namely the mathematical-physical subjects, mechanics, materials strength, electrical technology basics, and the manufacture technology basics.

Studies timetable for the Mechatronic Faculty, approved by the Council of the Mechanical Faculty at Wroclaw University of Technology While preparing the curriculum of the subject, the holistic approach to the problem was assumed, incorporating the term division in the division of the materials into units.

Thus, the dynamic mechanical response of these materials is especially important to grant the required level of protection to armor.
There are two main fracture modes of brittle materials under compression, namely: split mode and crushed mode.
This indicates that these flaws in the materials can decrease the strength of the material.

In their studies, the perfect interface between two different materials is assumed.
For perfect interface the state vector keeps unchanged across interface of two materials.

Polyurethane aqueous based adhesive presented better interaction with both materials when compared to organic solvent based adhesive.
The high resistance to fracture is related to the strong interactions between the materials [1, 2].
For achieving that, an adhesive layer must be introduced to bond the materials together.
