This study is based on cracks that occurred in metal beams obtained under controlled fatigue-crack propagation. The beams were clamped in a heavy vise and struck in order to obtain a clean impulse modal response. Spectrograms of the free-decay responses showed a time drift of the frequency and dampi

An iterative modal analysis approach is developed to determine the e!ect of transverse cracks on the dynamic behavior of simply supported undamped Bernoulli}Euler beams subject to a moving mass. The presence of crack results in higher de#ections and alters the beam response patterns. In particular,
