Radial Basis Functions and Improved Hyperparameter Optimisation for Gaussian Process Strain Estimation
A. W. T. Gregg, J. N. Hendriks, C. M. Wensrich +1
Over the past decade, a number of algorithms for full-field elastic strain estimation from neutron and X-ray measurements have been published. Many of the recently published algori…
Bayesian Non-parametric Bragg-edge Fitting for Neutron Transmission Strain Imaging
Johannes Hendriks, Nicholas O'Dell, Adrian Wills +3
Energy resolved neutron transmission techniques can provide high-resolution images of strain within polycrystalline samples allowing the study of residual strain and stress in engi…
Energy Resolved Neutron Imaging for Strain Reconstruction using the Finite Element Method
Riya Aggarwal, Mike Meylan, Bishnu Lamichhane +1
A pulsed neutron imaging technique is used to reconstruct the residual strain within a polycrystalline material from Bragg edge strain images. This technique offers the possibility…
Neutron Diffraction Strain Tomography: Demonstration and Proof-of-Concept
A. W. T. Gregg, J. N. Hendriks, C. M. Wensrich +2
Recently, a number of reconstruction algorithms have been presented for residual strain tomography from Bragg-edge neutron transmission measurements. In this paper, we examine whet…
Neutron diffraction strain tomography: 2D axisymmetric sample geometry
V. Luzin, A. W. T. Gregg, J. N. Hendriks +1
We consider a method for neutron residual strain/stress analysis combining features of transmission strain tomography (e.g. through Braggs edge imaging) and neutron diffraction tec…
Tomographic Reconstruction of Triaxial Strain Fields from Bragg-Edge Neutron Imaging
J. N. Hendriks, A. W. T. Gregg, R. R. Jackson +6
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 transmissio…
