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

<div>Finite element models of flexible cracked annular thin disks (ai) four kinds of cracks, i = 1, 2, 3, 4, (bj) three shapes of RC-cracks, j = 1, 2, 3. (a1) RO-crack (RO20), (a2) RC-crack (RC20), (a3) CF-crack (CF60), (a4) TG-crack (TG32), (b1) rectangle crack, (b2) round-rectangle crack, and (b3) diamond crack.</div>
