Abstract
The torsional vibrations of a rotor with a transverse crack are invest igated. The crack is modelled by way of a local flexibility matrix whi ch is calculated analytically and measured experimentally. Good agreem ent between the two methods is obtained. The free vibration problem is solved and the three first eigenvalues are plotted versus the crack l ocation and depth. The finite element method is used for the solution of any shaft system with a crack, using a modified stiffness matrix fo r the cracked element.
