Opis:: The results of experimental and numerical analysis of the influence of the non-axisymmetric pulse shaper position on recorded wave signals in the split Hopkinson pressure bar experiment are presented. The paper focuses attention on the problem of wave signal disturbances caused by a bending wave resulting from non-axisymmetric pulse shaper positions and, moreover, different shaper thickness, striker impact velocities and Wheatstone bridge configurations. The obtained results of analyses indicate that the effect of the non-axisymmetric pulse shaper position may be neglected if deviation from the bar axis does not exceed 20%.

Opis:: The paper presents a method of assessing of ballistic resistance of four armor steels based on the results of shear tests under dynamic load conditions. All shear tests were performed using a newly developed flat material specimen with two shear zones. High strain-rate experiments were performed using the spilt Hopkinson pressure bar technique. In addition, the V50 ballistic resistance tests for the armor steels were carried out. The maximum value of the shear strain energy density (SSED) was adopted as the evaluation criterion. The SSED parameter takes the highest average value for the armor steel with the highest ballistic resistance.

Opis:: The magnetorheological fluid is a functional material that is changing its rheological properties and finally solidifies in a magnetic field. The dynamic behaviour, tested with the use of the Split Hopkinson Pressure Bar is an important issue for description of this material, which is commonly used in different kinds of shock absorbers. This note presents a new idea how to modify the known SHPB set up in order to investigate dynamic properties of magnetorheological materials.
