Experimental Study on Split Hopkinson Pressure Bar Pulse-Shaping Techniques for Concrete
Publication: Journal of Materials in Civil Engineering
Volume 28, Issue 5
Abstract
The dynamic compressive behavior of concrete is investigated using a variable cross section straight taper split Hopkinson pressure bar (SHPB) apparatus in this study. In order to reduce and eliminate the waveform dispersion effect, two pulse shaping techniques are adopted to improve the incident wave shape. The two techniques include changing the striker (length, shape) and copper pulse shapers (diameter, thickness, shape). Experimental results show that the pulse shaping effect with the small diameter of copper shaper is better than that of the tapered striker and annular pulse shaper, all of which could reach dynamic stress equilibrium, and reduce the high-frequency oscillation, and achieve constant strain-rate deformation approximately.
