Bragg-edge elastic strain tomography for in situ systems from energy-resolved neutron transmission imaging
Abstract
Strain tomography has the potential to dramatically transform the way in which experimental mechanics is carried out. In much the same way that regular computed tomography transformed medicine and other sciences, a full-field approach to measuring triaxial strain may have an impact across a range of areas. This paper details a practical demonstration of reconstructing a biaxial elastic strain fields from Bragg-edge neutron strain images in a nontrivial steel sample subject to $i{{0}{0ex}}n$ $s{{0}{0ex}}i{{0}{0ex}}t{{0}{0ex}}u$ loading. This demonstration provides a basis for future efforts focussed on extending to three-dimensional strain fields, as well as a broader class of strain fields (e.g., residual strain).
