Fiber Bragg Gratings, IT Techniques and Strain Gauge Validation for Strain Calculation on Aged Metal Specimens
This paper studies the feasibility of calculating strains in aged F114 steel specimens with Fiber Bragg Grating (FBG) sensors and infrared thermography (IT) techniques. Two specimens have been conditioned under extreme temperature and relative humidity conditions making comparative tests of stress before and after aging using different adhesives. Moreover, a comparison has been made with IT tec...
متن کاملNonlinear Fiber Bragg Gratings
In this paper we review some of the dominant topics in fiber Bragg gratings (FBGs). The combination of theory and simulations shows that these structures can use in filters, nonlinear fiber optical applications, soliton propagations etc. We discussed the theory of FBGs, grating solitons, Bragg soliton generation in intrinsic media and birefringence effects in FBGs together with some numerical s...
متن کاملPrinciples and Application of Polyimide Fiber Bragg Gratings for Surface Strain Measurement
Although theoretical investigation has demonstrated that fewer strain transfer layers imply a greater strain transfer ratio, as well as increased accuracy, most researchers are still focused on investigating encapsulated Fiber Bragg gratings (FBGs) in surface strain measurements. This is because, in a traditional view, bare FBGs are too fragile to be mounted on the substrate for measuring surfa...
متن کاملStrain Measurement in Aluminium Alloy during the Solidification Process Using Embedded Fibre Bragg Gratings
In recent years, the observation of the behaviour of components during the production process and over their life cycle is of increasing importance. Structural health monitoring, for example of carbon composites, is state-of-the-art research. The usage of Fibre Bragg Gratings (FBGs) in this field is of major advantage. Another possible area of application is in foundries. The internal state of ...
متن کاملBulk regeneration of optical fiber Bragg gratings.
The reliability and reproducibility of regenerated gratings for mass production is assessed through simultaneous bulk regeneration of 10 gratings. The gratings are characterized and variations are compared after each stage of fabrication, including seed (room-temperature UV fabrication), regeneration (annealing at 850°C), and postannealing (annealing at 1100°C). In terms of Bragg wavelength (λ(...
