- There are elaborated some dependences which make it possible to compute some materials resistant to hits with the energy greater than in so far tests of the bullets of 7,62 mm caliber. The tests of being resistant to hit have been carried out with the 10GHMBA steel which has been overshot by the bullets of 12.7 mm. In order to do that the single cover plates with changeable thickness have been placed in the ballistic pendulum. On the basis of the obtained measurements like speed before and behind the specimen, the pendulum deflection angle, the force passed to the dynamometer sleeve, it is possible to define the maximum thickness of the penetrated material. The comparison with the bullets proof of various materials like steel with composites, ceramics or the mathematical models verification by an experiment can be done with direct comparison of some chosen measured parameters. For example the bullet speed behind the specimen has to be related to its thickness similarly to some other parameters which are possible to be measured. All the quantities like the bullet speed behind the specimen are the functions of the specimen thickness for the defined type of bullet. The penetration process of the material is a kind of transformation of the energy carried by the bullet into the energy of the specimen deformation, the emitted warm or into the pendulum work. In order to compare the bullet proof with various materials or the mathematical models with experiment there is proposed getting in some non-dimensional factors which define the change of the kinetic energy or the system impulse.
