An essay on in neutron-based strain measurement techniques: equilibrium-based methods for non-destructive estimation
Christopher Wensrich, Giles Parkes, Vladimir Luzin +2
Determination of the stress-free reference lattice spacing, , is a central and often underestimated difficulty in diffraction-based strain measurement. Although commonly treat…
Well-posedness and trivial solutions to inverse eigenstrain problems
Christopher Wensrich, Sean Holman, William Lionheart +4
We examine the well-posedness of inverse eigenstrain problems for residual stress analysis from the perspective of the non-uniqueness of solutions, structure of the corresponding n…
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…
Tomographic Reconstruction of Two-Dimensional Residual Strain Fields from Bragg-Edge Neutron Imaging
Alexander Gregg, Johannes Hendriks, Christopher Wensrich +7
Bragg-edge strain imaging from energy-resolved neutron transmission measurements poses an interesting tomography problem. The solution to this problem will allow the reconstruction…
