Crack detection at an early stage can prevent catastrophic failures. In this thesis, the inverse problem of crack detection in frames is studied. The direct problem of calculating the natural frequencies of beams and frames with multiple cracks is first tackled.
Anew method for natural frequency calculation is devised. the cracks are modelled as rotational springs.
