Abstract: 

In this paper, a finite element model is formulated for dynamic analysis of beams containing two parallel and unequal edge-cracks. First, by using the compliance matrix concept, which accounts for the effect of local flexibility due to the presence of crack in the structure, the stiffness matrix is calculated for a beam element with one edge-crack. The effects of crack depth and its location on the first and third natural frequencies of the beam are investigated. The same model is then extended for an element with a double edge-crack of unequal lengths. Considering the interaction between cracks, the influence of crack depth on free vibration of the beam is investigated. Finally, a new model is developed for a beam element containing two parallel edge-cracks. It is shown that the vibrational behavior of beam is significantly influenced when the second crack approaches the first one.
