Delamination identification of CFRP structure using discriminant analysis via the support vector machine

open access: yesNihon Kikai Gakkai ronbunshu, 2014
This paper is about damage diagnosis using discriminant analysis via the support vector machine(SVM). For evaluation of reliability of the structure, condition of the structure is divided to several condition levels by the threshold in many cases.

Localization of transversal cracks in sandwich beams and evaluation of their severity [PDF]

open access: yes, 2014
An algorithm to assess transversal cracks in composite structures based on natural frequency changes due to damage is proposed. The damage assessment is performed in two steps; first the crack location is found, and afterwards an evaluation of its ...

Partial‐Model‐Based Damage Identification of Long‐Span Steel Truss Bridge Based on Stiffness Separation Method

open access: yesStructural Control & Health Monitoring
Damage detection in bridge structures has always been challenging, particularly for long‐span bridges with complex structural forms. In this study, a partial‐model‐based damage detection method was proposed for the damage identification of long‐span ...

Dynamic characterisation of a damaged composite structure with stiffeners employing fibre bragg gratings [PDF]

open access: yes, 2011
One of the key issues in composite structures for aircraft applications is the early detection and localisation of damage. Often service induced damage does not involve visible plastic deformation, but internal matrix related damage, like transverse ...
