Caption: Examples of UAS-based geospatial outputs at Beyer Road Bridge Left: The green polygons show likely delamination
areas as detected by automated methods and the pink polygons are delamination
marked by a MDOT bridge survey a month after the UAV thermal data collection.
The amplitude difference between reflection from delamination
and not defected area is 1 dB.
A different failure mode has occurred when using thicker film material where delamination
occurs during soldering.
persists mostly unchanged through Gates 12, 13, and 14, and finally begins to disappear in Gate 1 5.
Effect of delamination
on buckling performance of FRP composite plates.
However, the bottom surface displays a significant amount of wrinkles and defects within the laminate the use of NDT has allowed us to identify the range of delamination
's caused by the forming operation without changing settings or location of the NDT system, It has additionally enabled us to perform a repeatable quality control step on a variety of composite stacks with varying defects of variable size and ability to identify with no delamination
in surface A to severe delamination
see in Surface D Figure 6.
In this paper, a numerical approach is proposed to localize a delamination
in sandwich skin as presented in Figure 1.
crack is, generally, represented by an interfacial entity between two plies of the laminates.
factor is labelled as Df and it is the percentage difference between the recommended width of the notch and the real width of the notch.
More specifically, the outermost area accounts for the whole extension of delamination
. In fact, as demonstrated in previous work , any form of damage (delamination
and/or fibers breakage) is accompanied by heat dissipation, which manifests itself through the appearance of hot spots/areas over the material surface.
S.M Kulkarni et al  analyzed drilling induced delamination
in GFRP across various cutting parameters and concluded the optimum cutting parameters obtained using ANOVA and Taguchi methods.
Compared to coatings made with competitive products, hybrid formulations featuring SiVance C2010 resin enable formulators to help their customers avoid the cracking, delamination
and blistering that lead to corrosion and failure of metal pipes, tanks and equipment, according to the company.
