General reconstruction of elastic strain fields from their Longitudinal Ray Transform
Chris Wensrich, Sean Holman, William Lionheart +4
We develop an algorithm for reconstruction of elastic strain fields from their Longitudinal Ray Transform (LRT) in either two or three dimensions. In general, the LRT only determin…

Direct inversion of the Longitudinal Ray Transform for 2D residual elastic strain fields
C. M. Wensrich, S. Holman, M. Courdurier +3
We examine the problem of Bragg-edge elastic strain tomography from energy resolved neutron transmission imaging. A new approach is developed for two-dimensional plane-stress and p…
