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 1.25 mm, 2.5 mm, and 3.75 mm, respectively. We generated 194 damages at different locations for each damage depth.
