Three-dimensional reconstruction of intragranular strain and orientation in polycrystals by near-field X-ray diffraction

Current Opinion in Solid State and Materials Science, 2020
Abstract A theoretical framework is proposed for simultaneous reconstruction of the three-dimensional grain shapes, intragranular strain and orientation fields inside polycrystals from near-field X-ray diffraction images, using box beam illumination.

A comparative study of techniques of distant reconstruction of displacement and strain fields using the DISTRESS simulator [PDF]

Optik, 2016
Abstract Reconstruction and monitoring of displacement and strain fields is an important problem in engineering. We analyze the remote and non-obtrusive method of Digital Image Correlation (DIC) in 2D based on photogrammetry. The method involves covering the photographed surface with a pattern of speckles and comparing the images taken before and ...

Non-uniform strain field reconstruction of FBG using an adaptive Nelder–Mead algorithm

Optics Communications, 2021
Abstract This paper presents an adaptive Nelder–Mead algorithm to inversely reconstruct the non-uniform strain field from the reflected intensity spectrum of the fiber grating sensor. In this algorithm, the standard operating parameters are modified to adapt to the variable strain profiles, and an improved transfer matrix method is adopted to rapidly

Strained Field of Silver Overlayers Deposited on the Reconstructed Si(111) Surface

MRS Proceedings, 1992
ABSTRACTWe have performed high resolution x-ray diffraction measurements of the strain field in UHV deposited Ag(111) films on a 7×7 reconstructed Si(111) surfaces shows a faulted epitaxial layer with a 0.4% out-of-plane strain, and a -1% in-plane strain.
