The presence of a crack in a structural member introduces a local flexibility that affects its
vibration response. Moreover, the crack will open and close in time depending on the …

This article concerns infinitesimal free vibrations of undamped elastic systems of finite
extent. A review is made of the literature relating to the unique reconstruction of a vibrating …

Considering the existence of the opening crack, the axially motion as well as the transverse
harmonic excitation, the dynamic response of the beam is studied by a structure-preserving …

The present work aims to assess the modal properties of reinforced concrete structures
strengthened with FRP-based systems subjected to progressive damage. In particular, an …

A new simplified approach to modelling cracks in beams undergoing transverse vibration is
presented. The modelling approach uses Euler–Bernoulli beam elements with small …

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. The main feature of this …

This paper addresses the problem of vibrations of a cracked beam. In general, the motion of
such a beam can be very complex. This phenomenon can be attributed to the presence of …

Multiple damage identification in beams using curvature mode shape has become a
research focus of increasing interest during the last few years. On this topic, most existing …

Centrifugal pumps are widely used in modern industry, and blades are the key parts of it.
The cracks on blades may result in a very serious consequence. In this paper, a fault …

A method for detection of multiple open cracks in a slender Euler–Bernoulli beams is
presented based on frequency measurements. The method is based on the approach given …
