Detection of multiple cracks using frequency measurements
D.P. Patil,Surjya Kumar Maiti +1 more
TL;DR: In this paper, a method for detection of multiple open cracks in a slender Euler-Bernoulli beams is presented based on frequency measurements, where the beam is virtually divided into a number of segments, which can be decided by the analyst, and each of them is considered to be associated with a damage parameter.

Free vibration analysis of a cracked beam by finite element method
D.Y. Zheng,Nicole F Kessissoglou +1 more
TL;DR: In this paper, the stiffness matrix obtained using the overall additional flexibility matrix can give more accurate natural frequencies than those resulted from using the local additional flexibility matrices, and the authors constructed a shape function that can perfectly satisfy the local flexibility conditions at the crack locations.

Natural frequencies of a beam with an arbitrary number of cracks
E.I. Shifrin,Romualdo Ruotolo +1 more
TL;DR: In this article, a new technique is proposed for calculating natural frequencies of a vibrating beam with an arbitrary finite number of transverse open cracks, and the main feature of this method is related to decreasing the dimension of the matrix involved in the calculation.
