Identification of Crack Flaw in Beams

The vibration behavior of a cracked simply supported beam is investigated. The beam is modeled as an Euler- Bernoulli beam with rectangular cross section. The analytical solutions are capable of detecting location of cracks and other possible structural flows on a beam by using its first natural frequency. The effects of the location and depth of the crack on the natural frequencies, and mode shapes of the beam are investigated. Detection of the crack location using natural frequencies as the main parameters is also discussed.
