A finite element model is used for flexural vibration analysis of a static (non-rotating) rotor with two open cracks, and the stiffness matrices of the cracked elements are obtained using transfer matrix analysis and local flexibility theorem. Through numerical simulation, the effects of the slenderness ratio and the crack depth on the mode shapes and the changes in the eigenfrequencies of the cracked...
A finite element (FE) model, which is based on transfer matrix analysis and local flexibility theorem, is introduced for crack identification of a static (non-rotating) rotor with an open crack. Through numerical simulation, the effects of the location and depth of the crack on the mode shapes and the changes in the eigenfrequencies of the cracked rotor are investigated, and the ratio of the changes...
