NCAL: Diffraction Stress Measurement Under Applied Load

Ongoing
Using X-ray diffraction (XRD) techniques one can measure the full stress tensor just inside the surface of a sheet metal specimen under applied loading. This permits the measurement of biaxial stress states resulting from directly applied deformation (see NCAL: Multiaxial Material Performance) or
