Theoretical and Experimental Modal Analysis

Abstract: An elongated fishing lure formed, in the preferred embodiment, entirely of a soft, elastic, flexible and resilient plastic material which results in a lure freely deformable or manipulable under external forces. The lure includes an elongated body, a head at one end and a tail at the second end, with a series of integral outwardly projecting ribs at closely spaced points along the body, which ribs perform multiple significant functions including the selective trapping and release of air, the generation of clear acoustical signals, the increase in the visual bulk of the lure without affecting the flexibility thereof, the provision of means for facilitating movement of the lure over obstacles, etc.

A review of vibration-based structural health monitoring with special emphasis on composite materials

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.

Vibration Based Condition Monitoring: A Review:

Abstract: Vibration based condition monitoring refers to the use of in situ non-destructive sensing and analysis of system characteristics –in the time, frequency or modal domains –for the purpose of detecting changes, which may indicate damage or degradation. In the field of civil engineering, monitoring systems have the potential to facilitate the more economical management and maintenance of modern infrastructure. This paper reviews the state of the art in vibration based condition monitoring with particular emphasis on structural engineering applications.

Vibration–based structural damage identification

Abstract: Many aerospace, civil and mechanical systems continue to be used despite ageing and the associated potential for damage accumulation. Therefore, the ability to monitor the structural health of thes...
