Abm'act--The torsional vibrations of a rotor with a transverse crack are investigated. The crack is modelled by way of a local flexibility matrix which is calculated analytically and measured experimentally. Good agreement between the two methods is obtained. The free vibration problem is solved and

The effect of the presence of the single transverse crack on the response of the rotor has been a focus of attention for many researchers. In the present work a simple Jeffcott rotor with two transverse surface cracks has been studied. The stiffness of such a rotor is derived based on the concepts o

The dynamic behaviour of structures, in particular, that of a rotor, containing cracks is a subject of considerable current interest. Several researchers have developed models of cracked rotor systems considering mainly a single transverse surface crack. In the present study Finite Element (FEM) ana

The subcritical growth of semi-elliptical surface cracks in the front face of a cylindrical disk was calculated. The disk represents a part of a turbine rotor. The stress intensity factors, which are the basis for the calculations presented here, were given in a former paper [l]. The load steps cons
