Apparatus and method for in-situ measurement of residual surface stresses |
摘要 |
An apparatus for in-situ measurement of residual surface stresses comprises a compact x-ray tube and a detector. X-rays emitted by the x-ray tube are diffracted from a specimen surface and intercepted by the detector. The intercepted x-rays are converted into light and transferred by a first fiber optic bundle and a second fiber optic bundle to light detection devices. Intensities of the received light are digitized by the light detection devices to generate a first ring and a second ring with common centers. The residual stress in the specimen surface is calculated based on a difference between the radii of the first ring and the second ring.
