Abstract

The relationship between grain scattering and uniaxial stress has recently been theoretically developed [1]. The scattering results because of reflections at grain boundaries and discontinuities in the microstructure. The acoustoelastic response of individual grains due to temperature and stress gradients has a direct influence on the strength of the scattering. Measurements of mechanically-induced uniaxial compressive stress on a rail section and thermal stresses within continuously welded rail (CWR) were performed. It was found that this technique can produce measurement resolution of at least 10 -4/MPa.
