A method of computational modelling is applicd for invcstigation of influence of transverse fatigue crack located in the midspan of rotor system RK 4. The response of rotor system RK 4 is computed from equations of motion derived in the rotor-fixed co-ordinate system utilizing the Runge-Kutta method of the 4th order. The influence of the crack in rotor system is investigated by means of frequency spectra obtained from time domain response.
