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, rotors containing cracks-is a subject of considerable current interest. Several researchers have developed models of cracked rotor systems considering mainly the transverse surface crack. In the present study finite element (FEM) analysis of a rotor
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
