MuDI: A Multilevel Damage Identification Platform

Civil-Comp Proceedings, 2014
This paper present the ideas and methods that are behind the development of a multilevel damage identification platform (MuDI). The need to develop the platform is a consequence of the collaboration of some of the authors with the Italian Department of Civil Protection, that has a large project named Seismic Observatory of Structures, in which more ...

Vibration–based structural damage identification

Philosophical Transactions of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 2001
Many aerospace, civil and mechanical systems continue to be used despite ageing and the associated potential for damage accumulation.

Dynamic Response as a Tool for Damage Identification

International Applied Mechanics, 2004
Summary: The change of dynamic characteristics is used to determine the magnitude and location of damage or other imperfections. The applied technique of change of surface curvature mode is compared with other methods. Examples of identification of real structures and models are considered.

Identification of Fragmented Pictures in Patients With Brain Damage

Applied Neuropsychology, 1998
Identification of fragmented pictures was investigated using line drawings (Snodgrass, Smith, Feenan, & Corwin, 1987) in 236 healthy participants and 43 patients with unilateral lesions of the right or left hemisphere. Perceptual closure (the integration of fragments into a meaningful perceptual whole) depended on the amount of physical visual ...

Substructure damage identification using damage tracking technique

SPIE Proceedings, 2007
A challenging problem in structural damage detection based on vibration data is the requirement of a large number of sensors and the numerical difficulty in obtaining reasonably accurate results when the system is large. To address this issue, the substructure identification approach may be used.

Prompt damage identification for system survivability

International Journal of Information and Computer Security, 2008
Survivable systems must identify and isolate any damage as quickly as possible to avoid infection epidemic and outbreak in case of a malicious attack. Any delay during the fault detection and isolation process may lead to system unavailability and is unacceptable in mission-critical applications.

Automated in-service damage identification

CIRP Annals, 2014
Abstract Service damage for mechanical components includes surface delamination, impact damage, crack, wear and corrosion. Automated service damage identification for better analysis of a component remaining life in order to reduce the service cost is increasingly necessary for industrial product-service systems, e.g. power-by-hour contracts.

Damage identification in Euler frames

Computers & Structures, 2012
The present paper examines the effect of local damage in elastic frames composed by Euler beams. The direct problems of undamaged and damaged frames are studied using the Wittrick-Williams algorithm. The related inverse problems of identifying material parameters in the undamaged structure and damage parameters, i.e.

Damage Identification in Composite Panels—Methodologies and Visualisation

2015
A methodology for the identification of an impact damage using guided waves on a composite structure is implemented. Both numerical and experimental results are used, and a graphical user interface is developed to visualise the potentially damaged area.

Identification of coexistent load and damage

Structural and Multidisciplinary Optimization, 2009
Load reconstruction and damage identification are crucial problems in structural health monitoring. However, it seems there is not much investigation on identification of coexistent load and damage, although in practice they usually exist together. This paper presents a methodology to solve this problem based on the Virtual Distortion Method. A damaged
