摘要：
The present research article investigates the effect of a transverse crack on the flexural vibration of fiber reinforced composite beam based on Euler-Bernoulli beam theory. The presence of a crack in structural elements leads to an energy concentration near to crack's region and introduce a local flexibility which affect its dynamic response. Linear fracture mechanic theory has been used for crack modeling by using the stress intensity factors expressions. A parametric study has carried out in order to investigate the influence of fiber orientation, crack depth and crack location on the natural frequencies and theirs corresponding shape modes.
