摘要：

The paper presents a mathematical model of transverse vibrations of a Bemoulli-Euler beam with a closing crack. In damaged cross-sections of the beam there were applied elastic elements of flexibility calculated on the basis of the laws of fracture mechanics. Making use of the elaborated model, an analysis of the effect of magnitude and position of the crack upon the basic instability area of the beam was carried out.
