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

open access: yesApplied 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.

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

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.

Displacement field reconstruction technique for plate-like structures based on model superposition method

open access: yesMeasurement + Control, 2023
To achieve real-time sensing and deformation reconstruction of flexible plate structure, a 3D reconstruction technique based on a quasi-distributed fiber grating sensor network and order-optimized modal superposition method is proposed.

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].

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.
