TL;DR: In this paper, a finite element scheme for computing the eigensystem for a cracked beam for different degrees of closure was developed, where the finite element method, the component mode synthesis method and the linear elastic fracture mechanics theory were integrated for modelling of the cracked structures.

TL;DR: In this paper, the vibrational characteristics of a cracked Timoshenko beam are analyzed using the finite element method and component mode synthesis, where the beam is divided into two components related by a flexibility matrix which incorporates the interaction forces.

TL;DR: In this article, the effects of cracks on the dynamical characteristics of a cantilever composite beam, made of graphite fibre-reinforced polyamide, were investigated. And the results of the study lead to conclusions that, presented method is adequate for the vibration analysis of cracked cantileve composite beams, and by using the drop in the natural frequencies and the change in the mode shapes, the presence and nature of cracks in a structure can be detected.

TL;DR: In this paper, the authors presented a novel numerical technique applicable to analyze the free vibration analysis of uniform and stepped cracked beams with circular cross-section, in which the finite element and component mode synthesis methods are used together, the beam is detached into parts from the crack section.

TL;DR: Structural health monitoring and damage detection techniques are tools of great importance in the off-shore, civil, mechanical and aeronautical engineering communities, both for safety reasons and because of the economic benefits that can result.
Abstract: Structural health monitoring and damage detection techniques are tools of great importance in the off-shore, civil, mechanical and aeronautical engineering communities, both for safety reasons and because of the economic benefits that can result. The need to be able to detect damage in complex structures has led to the development of a vast range of techniques, of which many are based upon structural vibration analysis. In the present article, some of the latest advances in Structural Health Monitoring and Damage Detection are reviewed, with an emphasis on composite structures on the grounds that this class of materials currently has a wide range of engineering applications. FOREWORD-It should be noted that this review is not intended to be a general, all-encompassing review covering the whole range of structural health monitoring (SHM); it was planned as the starting point for a study focusing on damage detection, localization and assessment for certain kinds of structure. Thus, the line of thought behind the search and the structure of this review is a result of objectives beyond the scope of the paper itself. Nevertheless, it was considered that, once the above was understood, an updated synopsis such as this could also be useful for other researchers in the same field. ©2006 SAGE Publications.

TL;DR: A number of problems that exist with the use of inverse methods in damage detection and location, including modelling error, environmental effects, damage localization and regularization are discussed.
Abstract: This paper gives an overview of the use of inverse methods in damage detection and location, using measured vibration data. Inverse problems require the use of a model and the identification of uncertain parameters of this model. Damage is often local in nature and although the effect of the loss of stiffness may require only a small number of parameters, the lack of knowledge of the location means that a large number of candidate parameters must be included. This paper discusses a number of problems that exist with this approach to health monitoring, including modelling error, environmental effects, damage localization and regularization.
