✦ Synopsis

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) analysis of a rotor system for ¯exural vibrations has been considered by including two transverse open cracks The eigenvalue analysis and stability study of a rotor system including a shaft with two open cracks have been carried out and the in¯uence of one crack over the other for eigenfrequencies, mode shapes and for threshold speed limits has been observed.

A wide spectrum of investigations devoted to the determination of natural frequencies and mode shapes of beams with an open crack are presented in the literature. However, as is well known, an open crack is a fairly crude model of a fatigue crack. The study of the dynamic characteristics of a beam w
