Identification of defects in structures and its components is a crucial aspect in decision
making about their repair and total replacement. Failure to detect the faults has various …

Focus has been made to give an overview of various methodologies used in fault diagnosis
and condition monitoring. A crack in vibrating structures can lead to premature failure if it is …

A new method is proposed to obtain the eigenfrequencies and mode shapes of beams
containing multiple cracks and subjected to axial force. Cracks are assumed to introduce …

In this paper, the application of the bees algorithm (BA) to the problem of crack detection in
beams is introduced. A numerical as well as an experimental study is designed to predict a …

This paper presents a novel numerical technique applicable to analyse the free vibration
analysis of uniform and stepped cracked beams with circular cross section. In this approach …

This paper investigates the in-plane linear dynamic behaviour of multi-stepped and multi-
damaged circular arches under different boundary conditions. Cracked cross-sections are …

A technique based on measurement of change in natural frequencies and modeling of crack
by rotational spring is employed to detect a crack with straight front in different orientations in …

In this article, the purpose is to investigate the changes in the magnitude of natural
frequencies and modal response introduced by the presence of a crack on an axially loaded …

The detection of cracks in functionally graded material (FGM) structural members has been a
significant subject due to their increasing applications in various important engineering …

This study investigates the effect of damage on beams with fixed boundary conditions using
Fourier analysis of mode shapes in the spatial domain. A finite element model is used to …
