Natural frequency evolution due to damage for a fixed-free steel beam

We provide data that represent the first ten natural frequencies for the transverse (out-of-plain) vibration modes for a steel cantilever beam in an intact and damaged state. Simulation is made using ANSYS; we use a mesh made with hexahedral elements that have the maximum edge dimension 2 mm. The beam has the length 1000 mm, the width 50 mm, and the thickness of 5 mm. The damage is an open crack that has the distance between its faces 2 mm, and the depth reducing in nine steps the beam thichness (for instance the damage with depth 1.25 mm reduces the thickness with 25% and this feature is used to characterize it). We generated 194 damages at different locations for each damage depth.
