Damage detection in a sandwich composite beam using wavelet transforms
Dawood, TA; Shenoi, RA; Veres, SM; Şahin, Melin; Gunning, MJ (2003-01-01)
There is a growing interest in developing non-destructive damage detection methods for damage assessment of composite structures, especially in the aerospace and marine industries. Although damage detection of composite laminates has been widely investigated, little work has been carried out on sandwich composite configurations. A technique using the Lipschitz exponent, which is estimated by wavelet transforms, as a damage sensitive signal feature is outlined here to identify damage in sandwich composites. ...
Damage Characterisation in FRP Sandwich Beams using a Wavelet based Multifractal Approach
Dawood, Tariq; Shenoi, Ajit R.; Veres, S. M.; Gunning, M. J.(2004-07-07)
Fibre reinforced plastic (FRP) sandwich composite materials are widely used in the construction of aerospace and marine structures. A cause for concern however in the use of these materials is the fact that internal defects can occur between layers which, if not identified early on, can lead to rapid structural degradation. This paper describes an approach, based on measuring structural vibration characteristics, to identify these internal defects. The idea being that an occurrence of a defect of this natur...

Damage Progression in Thick Curved Composite Laminates under Static and Fatigue Loading
Tasdemir, B.; Çöker, Demirkan (IOP Publishing; 2018-06-22)
In this study, damage behavior of curved carbon fiber reinforced polymer (CFRP) composite laminates that are important sub-structures (ribs, shear webs and spar flanges etc.) for wind turbine blades are investigated under static and fatigue loading conditions. Cross-ply curved specimen consisting of groups of three 0 degrees and 90 degrees layers is used for clear observation of the matrix cracking in thicker plies. Damage mechanisms and locations under static and fatigue loadings are examined. In the exper...
Damage diagnosis in frame structures with a dynamic response method
Akgün, Müşerref Asuman; Ju, Fudong (Informa UK Limited, 1990-6)
The dynamic response of planar frame structures composed of damped Bernoulli-Euler beams is computed, with and without a crack present in the structure. The inertance changes due to the crack are investigated in relation to the crack location, with the aim of developing a diagnosis method. The optimum excitation location and frequency and the optimum locations for response measurement are determined for best diagnosis results. The effects of crack location and severity and of damping are investigated. Dampi...
