Abstract
Free vibrations of elastic arches with rectangular cross sections are studied. The arches under consideration have piece wise constant dimensions of the cross section. Moreover, the arches are weakened with cracks of given extension. The influence of crack parameters on the natural frequencies is established by the method of a rotational spring.
