A systematic investigation was performed to estimate the dynamic stress of fan blisk. Modal analysis was carried and the geometry nonlinearity was considered. The coupled Campbell diagram was obtained. The unsteady analysis was undertaken considering stators. The dynamic stress was obtained. The asymmetry stator design made dynamic stress dropped. The numerical results were validated by test.
