摘要: Abstract A finite element model is applied to the vibration and stability of thick rotating blades with a single edge crack. The effects transverse shear deformation rotatory inertia are taken into account. can satisfy all geometric natural boundary conditions blade. problems cracked blade subjected non-conservative follower forces considered. crack locations sizes on dynamic behavior studied. It found that change vibrational characteristics system.
