摘要：

The influence of transverse cracks on the coupled torsional and bending vibrations of a rotor is presented in this study. A fragment of the shaft of constant cross-section with a crack is modelled by means of a beam finite element. A procedure to calculate the stiffness coefficients in cross-sections weakned by cracks is given. The crack is considered to be open. The stiffness matrix for the above mentioned element is given. The method is illustrated by an example.
