Dispersion Correction for Split-Hopkinson Pressure Bar Data

Authors: L. E. Malvern; D. A. Jenkins; E. Jerome; J. C. Gong; FLORIDA UNIV GAINESVILLE DEPT OF ENGINEERING SCIENCES
Abstract:
Large diameter Split-Hopkinson Pressure Bar (SHPB) systems required a correction of the strain signals to account for wave dispersion. Using a Fast Fourier transform (FFT) algorithm a wave dispersion correction program was developed for the 3.0 inch diameter SHPB at the University of Florida and the 2. 0 inch diameter SHPB at Tyndall AFB FL. Since the data are applicable to only these two systems the report is published as a user's manual for these two systems. Keywords: Dispersion correction; Hopkinson bar;
