Importance of the model selection for processing dynamic three-point bending tests

Abstract : The Split-Hopkinson Pressure Bar apparatus remains the standard test to investigate high strain rate materials properties. To determine the tensile strength of quasi-brittle materials three-point bending tests are frequently employed. In this paper, we compare different analytical models for processing the recorded experimental wave signals. It is concluded that only the semi-infinite beam model and the modal superposition analysis with several modes are relevant to get precise strain rate and material dynamic characteristics
