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.

Attribute-based structural damage identification by few-shot meta learning with inter-class knowledge transfer

Structural Health Monitoring, 2020
Image archives of multi-class structural damages can be collected by manual inspection and then used for structural damage identification. On one hand, conventional image-processing-based approaches rely on optimal designs of hand-crafted feature ...

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

A Bayesian fusion method for composite damage identification using Lamb wave

Structural Health Monitoring, 2020
This study presents a novel method for composite damage identification using Lamb wave. A probabilistic integration of the elliptical loci method and the RAPID (reconstruction algorithm for probabilistic inspection of defects) in a Bayesian framework is ...

An effective deep feedforward neural networks (DFNN) method for damage identification of truss structures using noisy incomplete modal data

, 2020
Structural damage assessment is a challenging problem of study due to lack of information in data measurement and the difficulty of extracting noisy features from the structural responses.

Structural damage identification based on modal frequency strain energy assurance criterion and flexibility using enhanced Moth-Flame optimization

Structures, 2020
The development of structural damage identification based on dynamic characteristics has been suffering from certain issues, such as low computational efficiency and lack of high-sensitivity damage indicators.

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 based on convolutional neural network and recurrence graph for beam bridge

Structural Health Monitoring, 2020
Traditional statistical pattern identification methods, such as artificial neural network and support vector machine, have limited ability to identify minor damage of bridges.

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.
