RWE npower sparks interest in engineering…

Posted on 01 May 2009

The npower enthuse day recently rolled into Cramlington Learning Village in Northumberland, where over 50 students took part in a one-day educational experience.
The students, aged 13 to 14, participated in a range of interactive activities designed to help them think about the impact science and engineering has on their daily lives.
The students were encouraged to [...]

Eddy Current Applications

Suppression of the Lİft-Off Variable :
Suppression of the Lİft-Off variable is accomplished by simply selecting a test point D so that the distances D-C and D-A are equal. Thus a slight change in lift-off will not afect the over all reading. Of course the test point selected could lie anywhere along the line D-E. If the test [...]

Half-Angle Beam Spread:

Calculates the half-angle beam spread “Φ” for a given velocity “V”, frequency “F”, transducer diameter “D”, and “K”is constant.Beam spread is a measure of the whole angle from side to side of the main lobe of the sound beam in the far field. Beam divergence is a measure of the angle from one [...]

Ultra-sound, Frequency, Amplitude

Posted on 20 December 2008

Many devices use ultra-sonic sound, like toothbrushes, metal inspecting devices, and the scanners used for seeing an unborn child. Ultra-sound is just what it sounds like, an ultra high frequency of sound. Sound is just a form of energy moving, through the air, at least in most cases.Here are some terms about sound.
Wave: [...]

What is Radiographic Testing (RT)

Posted on 30 July 2008

(RT) Radiographic Testing, or industrial radiography, is a nondestructive testing (NDT) method of inspecting materials for hidden flaws by using the ability of short wavelength electromagnetic radiationphotons) to penetrate various materials. (high energy)
Either an X-ray machine or a radioactive source (Ir-192, Co-60, or in rare cases Cs-137) can be used as a source of [...]

Liquid Penetrant Testing

Posted on 01 July 2008

Principles
DPI is based upon capillary action, where low surface tension fluid penetrates into clean and dry surface-breaking discontinuities. Penetrant may be applied to the test component by dipping, spraying, or brushing. After adequate penetration time has been allowed, the excess penetrant is removed, a developer is applied. The developer helps to draw penetrant out of [...]

Ultrasonic testing (UT) of cementitious materials

Posted on 29 October 2007

Abstract Based on Biot’s theory of wave propagation in suspensions the utilization of the ultrasound technique for the analysis of the setting and hardening of cementitiousmaterials became very popular over the last years. This is well documented innumerous papers (for instance: SAYERS & DAHLIN [1993], BOUTIN & ARNAUD[1995] or D’ANGELO ET AL. [1996]). The [...]
