From: Negative potential energy content analysis in cracked rotors whirl response
Numerical simulation results in (a)–(f) and the corresponding experimental results in (g)–(l) of the potential energy content in the transient whirl response at different unbalance force angles for \(\alpha = 25{\text{ rad/s}}^{2}\) and \(\mu = 0.2\)(gray color for positive potential energy values).
