Free vibration of double-cracked uniform beam

Abstract

This paper considers free vibration analysis of double-cracked uniform beam under various boundary conditions. It is supposed that cracks stay opened due to vibrations. The Euler-Bernoulli beam model was considered by using the rigid segment method. Satisfactory agreement of the obtained results with the results of other was achieved. In the case of occurrence of larger errors, it was noticed that there is a problem of closing the crack, which deviates from the initial assumption.
