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

open access: yesJournal 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

open access: yesNanotechnology, 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.

Analysis of Deformation in an Aluminium Hull Impacting Water Free Surface

open access: yesFluids, 2022
Water impacts provide a challenge for a wide range of applications, from aerospace, to marine, mechanical and civil engineering, due to the complexity conveyed by the coexistence of impulsive loads, large local deformations and high-amplitude vibrations.

Coarse and Fine Two-Stage Calibration Method for Enhancing the Accuracy of Inverse Finite Element Method

open access: yesSensors, 2023
The inverse finite element method (iFEM) is a novel method for reconstructing the full-field displacement of structures by discrete measurement strain. In practical engineering applications, the accuracy of iFEM is reduced due to the positional offset of

Tomographic reconstruction of triaxial strain fields from Bragg-edge neutron imaging [PDF]

open access: yesPhysical Review Materials, 2019
This paper presents a proof-of-concept demonstration of triaxial strain tomography from Bragg-edge neutron imaging within a three-dimensional sample. Bragg-edge neutron transmission can provide high-resolution images of the average through thickness strain within a polycrystalline material.

Two-Step Calibration Method for Inverse Finite Element with Small Sample Features

open access: yesSensors, 2020
When the inverse finite element method (inverse FEM) is used to reconstruct the deformation field of a multi-element structure with strain measurements, strain measurement errors can lower the reconstruction accuracy of the deformation field. Furthermore,
