Essay

Based on the results of numerical investigations of forced vibrations of beams with different boundary conditions in presence of closing crack there was shown that the non-linearity of vibration response around the sub- and superharmonic resonances is strongly dependent on the crack parameters (size and location), damping level, driving force application point, asymmetry, and nonharmonicity but does not depend on sensor location.
