About materials testing with impact loading


RE: Materials testing with impact loading.
Posted by: Sergei Tsarik , E-mail: sergei.v.tsarik@usa.net, on August 08, 1999 at 10:49:16 :
Hello!
We have developed and have introduced an impact audio method and instrument AUD-01 for a control of strength of wood-shaving plates. I direct to you the prospectus of the instrument.The audio impact flaw detector AUD-01:

The flaw detector is intended for a nondestructive testing of products from nonmetallic materials: aviation constructions from composite materials, wood-shaving plates, plywood and other bonded constructions from wood. Detected imperfections(flaws) - disbond, stratification.
The instrument allows also to inspect by a nondestructive method strength on curving of products from nonmetallic materials, for example, fiberglass, plywood, wood-shaving plates.
In the instrument the audio impact method of a is realized. Difference of the given instrument is the simultaneous registration at once of two parameters of raised impact impulse of free oscillations of the plating: amplitudes "A" and frequency (period " Ò "). It essentially increases a reliability of a control. An apart from it the instrument is small-size, and has both network, and battery power supply.
The instrument has two operational modes: single measurements in isolated points of an inspected product; measurement in separate zones - in 10 points, about representation on indicators of average value of parameters "A" and "Ò" in the given zone. The second method is used for a control strength of the characteristics of products from nonmetallic materials.
The instrument is introduced in production of wood-shaving plates (Russia).

Technical characteristics of the instrument.

Method of energization of oscillations - impact.
Frequency of impacts, Hz - 10-20.
Range of analyzable frequencies, êÃö - 5-500.
Analyzable parameters - amplitude, own frequency of oscillations, fading.
The type of a converter an agent of oscillations of mechanical,impact operation, receiver - piezoelectric.
Indication of data - 2 digital liquid-crystal indicators: amplitudes "" and period "Ò" of oscillations, fading - on the oscillograph connected to an output(exit) of the instrument: single and average value of the inspected parameter on an inspected zone of a product.
Structure of the instrument - electronic block, power supply unit, audio converter.
Power supply of the instrument - battery (9V) and network.
Dimensions, mm - 200x120x180 (electronic block). A mass - 1,5kg (common).

Next generation for Phased Array UT is here now with FMC/TFM! Have higher resolution imaging, impr
...
oved signal to noise ratio, characterize, size and analyze defects better with access to several wave mode views and save raw FMC data for higher quality analysis.  Some of the benefits are:
  • Beautiful Image! Easier to understand what you're looking at
  • Completely focused in entire image or volume
  • Much easier to define setups before inspection
  • Easier to decipher geometry echoes from real defects
  • Oriented defects (e.g. cracks) are imaged better
  • See image from different wave modes from one FMC inspection
  • FMC data can be reprocessed/analyzed without going back to the field
