Abstract: Vibrations of elastic plate strips supported at two opposite edges and free at the other edges are studied. It is assumed that the thickness of the strip is piece wise constant whereas stable part-through cracks are located at the re-entrant corners of steps. Making use of the basic concepts of the fracture mechanics a method for determination of eigenfrequencies of stepped plates with cracks is developed. The influence of a crack on the behavior of the strip is modeled as a change of the local flexibility or as a distributed line spring. Numerical results are presented for strips with cracks and without any crack subjected to the tension applied at an edge of the strip.
