Estimating the potential crack location in short beams using experimental modal analysis

A non - destructive practical method to locate a crack in short beams is established by usnig modal sensitivity concept and frequenty data. The timoshenko beam theory is used , taking into account the effects of rotary inertia andshear deformation.
