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…
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…
Robust Inference of Two-Dimensional Strain Fields from Diffraction-based Measurements
