| Abstract: | The chaotic motion of an elastic shaft-disk rotor system including the geometric nonlinearity of the shaft with a transverse crack is investigated. The critical condition for the system to enter chaotic state is given by the Melnikov method. Meanwhile, whether the chaos occurs is determined by the Poincar'{e} map, phase portrait and time-displacement history diagram.
