Mobile Shearography for Ndt of Technical and Artwork Components

نویسنده

چکیده

With new carbon fiber technologies and other lightweight constructions in aircraft and automotive manufacturing, adapted examination designs and especially developed testing methods are necessary. Modern optical methods have attracted interest not only for laboratory investigations but also for applications on the factory floor because they can be sensitive, accurate, non-tactile and non-destructive. Shearography as a coherent optical method has been widely accepted as a useful NDT tool. This paper describes a complete mobile shearographic procedure including loading and image processing facilities for structural testing and flaw recognition on aircrafts. The mobile system was successfully tested, e.g. with the up-to-date EADS multirole combat aircraft Eurofighter. It will be shown that the technology is also suited for the optical investigation on cultural objects and sensitive artworks.

Investigation of Loading Parameters in Detection of Internal Cracks of Composite Material with Digital Shearography

Laser shearography is a speckle interferometric technique for full-field measurement of surface displacement derivatives. This technique has proved highly effective for nondestructive testing (NDT) of many kinds of material, especially composites. The key to the success of shearography as a NDT method is to impose an appropriate stress status on the object under test. In this paper mechanical l...

Failure Investigation of Hydrogen Blistering on Low-strength Carbon Steel

The current study assesses the root causes of hydrogen blisters on low strength carbon steel equipment. For this purpose, some experiments including hardness test, non-destructive test (NDT), metallography, and fractograpghy are conducted. The microstructure of two blisters is assessed by means of optical microscopy and scanning electron microscopy (SEM). The microstructural studies show that t...
