Referring to the name it is a splitted Hopkinson Pressure Bar. The Hopkinson Bar is related to its inventor Bertram Hopkinson (1914). He used it to analyze stone samples under dynamic load. Later his construction was improved by Davies (1948) [1] and Kolsky (1949) [2], who had the idea to split the bar and put a sample in between. The technique is used to measure a lot of different mechanical properties of a material e.g. the dynamic Young’s modulus, deformation behaviour or to chart the dynamic stress-strain diagram. Further applications are the measurement of the elastic wave and the analysis of the propagation of the wave [2]. In the last years there was still an interest in measuring dynamic properties with a SHPB. Nevertheless no comprehensive validation of the system exists. Another problem is that the stress and the strain in the sample are only calculated with simplified estimations. The aim of this paper is to give a first impression of important points validating the system. On account of different setups of the SHPB a validation of the used system is necessary. Hence it is important to look at the theory. Further in this paper the measurement results will be shown in a strain over time diagram.
