โฆ Synopsis
In this article a new technique is proposed for calculating natural frequencies of a vibrating beam with an arbitrary ยฎnite number of transverse open cracks. The main feature of this method is related to decreasing the dimension of the matrix involved in the calculation, so that reduced computation time is required for evaluating natural frequencies compared to alternative methods which also make use of a continuous model of the beam.

An exact approach for free vibration analysis of a non-uniform beam with an arbitrary number of cracks and concentrated masses is proposed. A model of massless rotational spring is adopted to describe the local #exibility induced by cracks in the beam. Using the fundamental solutions and recurrence
In this paper, we describe a numerical method for determining the location of a crack in a beam of varying depth when the lowest three natural frequencies of the cracked beam are known. The crack is modelled as a rotational spring and graphs of spring sti!ness versus crack location are plotted for e
