A continuous cracked beam vibration theory is used for the prediction of changes in transverse vibration of a simply supported beam with a breathing crack. The equation of motion and the boundary conditions of the cracked beam considered as a one-dimensional continuum were used. The eigenfrequency c

The vibration and stability characteristics of a cracked beam translating between "xed supports are investigated. Using Hamilton's principle and elementary fracture mechanics, the equations of motion for the beam are developed. Throughout this analysis it is assumed that the crack is shallow and alw

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 analytical transfer matrix method is used to solve the direct and inverse problems of simply supported beams with an open crack. The crack is modeled as a rotational spring with sectional flexibility. By using the Timoshenko beam theory on two separate beams respectively and applying the compatib
