Hi! I have just conducted a simple impact test.
Study: Pipe(Baton) whipping/impact on a stationary glass
Result: Energy Plot comparision
Comment: There is noise of low amplitudes even before the impact is happened. And also there are similarities of amplitudes (troughs & peak) for ALLIE & ALLKE plot. Did I miss something on my approach of this study? I referred to the pipe whipping plot from the documentation, they only have smooth plot there. Thank you!
