The problem of the forced harmonic vibration of a visco-elastic beam with a rectangular cross-section having a single edge crack in an arbitrary position is investigated by means of the Boundary Integral Equation Method (BIEM). In the analysis, the crack is simulated by an equivalent rotational spring, connecting the two segments of the beam. The BIEM formula is applied to each segment of the beam. Some simple problems of beams subjected to harmonic exitation are considered and the computed results are compared with the exact solutions. In order to demonstrate the efficiency of the proposed method, the more complicated cracked beams are analyzed, and the response curves of the system and the effects of the crack location and the depth are investigated.
