Blade manufacturing tolerance and wear in operation may induce mistuning, and mistuning
will lead to vibration localization which will result in destruction of bladed disk. Generally …

The mistuning pattern on a bladed disc is controlled in Part 2 of the two-part article either by
(i) imposing a small maximum allowable mistune according to the small mistuning approach …

The huge variation in forced vibration response levels of mistuned bladed discs, which are
bladed discs with slightly different blades, is investigated in this thesis. The issue is known …

Mistuning, imperfections in cyclical symmetry of bladed disks is an inevitable and perilous
occurrence due to many factors including manufacturing tolerances and in-service wear and …

Cyclically periodic structures, such as bladed disk assemblies in turbomachinery, are widely
used in engineering systems. It is well known that small uncertainties exist among their …

When interblade coupling is weak, the dynamic response of a bladed disk is very sensitive
to the presence of uncertainties. Excessive response variation can be very harmful. Previous …
