Templates for Calibrating Sound Speed and Poisson's Ratio of (Split) Hopkinson Bar via Dispersion Correction of Elastic Wave

Authors/Creators

Description

The Excel and Matlab templates herein can be used for calibrating the sound speed and Poisson’s ratio of (split) Hopkinson bar and direct impact Hopkinson bar via the iterative dispersion correction of an elastic wave. For this purpose, the program solves the Pochhammer-Chree equation by itself. Once the bar properties are calibrated, the templates can be used for dispersion correction of elastic wave traveling the bar.
