The dynamic behaviour of a beam with numerous transverse cracks is studied. Based on the equivalent rotational spring model of crack and the transfer matrix for beam, the dynamic sti!ness matrix method has been developed for spectral analysis of forced vibration of a multiple cracked beam. As a part
Starting from the governing di!erential equations of motion in free vibration, the dynamic sti!ness matrix of a uniform rotating Bernoulli}Euler beam is derived using the Frobenius method of solution in power series. The derivation includes the presence of an axial force at the outboard end of the b
