Strained Field of Silver Overlayers Deposited on the Reconstructed Si(111) Surface
MRS Proceedings, 1992ABSTRACTWe 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.

On reconstruction of strain fields from tomographic data
Inverse Problems, 2015A method of reconstruction of a strain tensor in a solid body was described that uses non-redundant data of the axial (longitudinal) and of the traceless normal ray integrals.

Advances in Structural Engineering, 2023
The inverse finite element method (iFEM) is a superior shape sensing methodology in the field of structural health monitoring. However, the standard iFEM for beams yields only displacements at iFEM nodes whose spatial resolution is limited by the number ...

High-Precision Static Strain Field Measurement Based on Dense Fiber Bragg Grating Array
2023 Asia Communications and Photonics Conference/2023 International Photonics and Optoelectronics Meetings (ACP/POEM), 2023We have achieved precise static strain field measurement and applied for 2D shape sensing by using DFBG array with 20 different wavelengths. The accuracy was high with $\boldsymbol{0.83}\ \boldsymbol{\mu}\boldsymbol{\varepsilon}$ strain sensing and 0.2 ...

Abstract Reconstruction of strain and displacement fields from surface images of materials and structures in the presence of discontinuities is a challenging task. Digital Image Correlation (DIC) – a commonly used technique to reconstruct displacement and strain fields when deformation is continuous – fails in the presence of discontinuities ...
