A Study on Mode Shape and Natural Frequency of Rotating Flexible Cracked Annular Thin Disk

<div>The vibration modes of rotating flexible annular thin disks with various cracks: (ai) flawless flexible disk, (bi) flexible disk with RO-crack of 20 mm (RO20), (ci) flexible disk with RC-crack of 20 mm (RC20), (di) flexible disk with CF-crack of 60 degrees (CF60), (ei) flexible disk with TG-crack of 32 mm (TG32), i is each vibration mode’s order, and i = 1, 2, …, 9.</div>
