An advanced neutron strain analyser SALSA is designed for actually performing diffraction measurements on "real" engineering components and is optimised for stress determination in metallic components

Deformations and diffraction Measuring residual stress via diffraction relies on a tight correlation between macroscopic deformations (the concern of engineers) and the variation of diffraction angles (what ... on of the corresponding diffraction angles. For a given family of atomic planes, the angle goes up for compression areas and down for ...
