T1 - Introduction in the system of the split Hopkinson pressure bar and validation of the method N2 - The Split Hopkinson Pressure Bar (SHPB) or Kolsky Bar is known as a method for analysing mechanical properties of a material under dynamic load. 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.

Objective of the presented projects is to increase the personal and technical safety in hazardous scenarios.

The assessment procedure applied by BAM is based on a series of full-scale drop tests with different drop heights and Container Orientations. In parallel dynamic FEM calculations are performed. The Container behaviour is monitored during the drop test by a large number of simultaneously triggered biaxial electrical strain gauges and uniaxial accelerometers in order to measure local strains at selected positions and to determine the kinematic behaviour and Orientation of the Container during the impact. Within a research project a dynamic Stereo photogrammetry approach was applied in a high-speed camera configuration to investigate the kinematic rigid body behaviour, relative local movements of the Container or its structural parts in 3D, respectively. In the following the results of this approach are presented. A comprehensive description how to use optica) methods in drop tests can be found in.
