Liquid Crystals in Nondestructive Testing
Applied Optics, 1968The cholesteric phase is associated with scattering effects that give rise to iridescent colors, the dominant wavelength being influenced by very small changes in temperature, which can be as large as 1000 A shift per degree. This unusually high temperature sensitivity has given rise to the use of the cholesteric phase as a sensitive thermometer and ...

A Nondestructive Testing Technique: Nail Penetration Test
2012This study presents a practical nondestructive testing (NDT) method: the nail penetration test (NPT). The major tools of the test technique are a gas nailer with 130 J (95.88 ft-lbf) power, concrete nails, and a gas nailer cell. The study covers three different limestone aggregate types.

The basis for the nondestructive testing of insulation
Electrical Engineering, 1941DIELECTRIC strength is the property of insulation that is most important to the operating power companies. The factor of safety determined by the ratio of breakdown voltage to operating voltage must be maintained. Yet this breakdown voltage cannot be measured on a finished piece of insulation.
