title = "Effects of elliptical crack shape ratio on transverse trajectory of a cracked shaft",
abstract = "Fatigue striations and beach marks seen on the cross-section of shafts subject to fatigue-induced failure reveal that the crack-front transitions from being highly rounded (elliptical/circular) to almost straight as the crack propagates. This study examines the transverse displacement of cracked rotors with varying elliptical crack shape ratios and depths, however, in particular, when the crack depth is increased, the elliptical crack shape ratio is also decreased. Furthermore, it is shown that straight-front cracks and elliptical-cracks models result in significantly different transverse trajectories at one-third and one-half of the critical speed. The findings of this study suggest that failure to account for the highly rounded nature of shallow cracks may result in large inaccuracies when predicting vibration behaviours of cracked rotors.",
