An optimization method for stochastic reconstruction from empirical data - A limestone rock strain fields study-case using digital image correlation data

MethodsX, 2023
Stochastic field reconstruction is a crucial technique to improve the accuracy of modern rock simulation. It allows explicit modelling of field conditions, often employed in uncertainty quantification analysis and upsampling and upscaling procedures ...

3D strain field reconstruction by inversion of dynamical scattering [PDF]

Applied Physics Letters
Strain governs not only the mechanical response of materials but also their electronic, optical, and catalytic properties. For this reason, the measurement of the 3D strain field is crucial for a detailed understanding and for further development of material properties through strain engineering.

General Reconstruction of Elastic Strain Fields from their Longitudinal Ray Transform [PDF]

SIAM Journal on Applied Mathematics
We develop an algorithm for reconstruction of elastic strain fields from their Longitudinal Ray Transform (LRT) in either two or three dimensions. In general, the LRT only determines the solenoidal part of a symmetric tensor field, but elastic strain fields additionally satisfy mechanical equilibrium, an extra condition that allows for full ...

Synchronized Full-Field Strain and Temperature Measurements of Commercially Pure Titanium under Tension at Elevated Temperatures and High Strain Rates

Metals, 2021
Understanding the mechanical behavior of materials at extreme conditions, such as high temperatures, high strain rates, and very large strains, is fundamental for applications where these conditions are possible. Although tensile testing has been used to

DIC-Aided Mechanoluminescent Film Sensor for Quantitative Measurement of Full-Field Strain

Sensors
To break through the bottleneck in the mapping of the mechanoluminescent (ML) intensity field to the strain field, a quantification method for full-field strain measurement based on pixel-level data fusion is proposed, integrating ML imaging with digital

Reconstructing intragranular strain fields in polycrystalline materials from scanning 3DXRD data [PDF]

Journal of Applied Crystallography, 2020
Two methods for reconstructing intragranular strain fields are developed for scanning three-dimensional X-ray diffraction (3DXRD). The methods are compared with a third approach where voxels are reconstructed independently of their neighbours [Hayashi, Setoyama & Seno (2017). Mater. Sci. Forum, 905, 157–164].

Reconstruction of three-dimensional strain field in an asymmetrical curved core–shell hetero-nanowire

Nanotechnology, 2023
Abstract Crystal orientation and strain mapping of an individual curved and asymmetrical core–shell hetero-nanowire (NW) is performed based on transmission electron microscopy. It relies on a comprehensive analysis of scanning nanobeam electron diffraction data obtained for 1.3 nm electron probe size.
