A new X-ray approach was proposed for determining the distribution of stress on the surface of a material using an imaging plate (IP). In this method, the computerized tomography (CT) was applied to stresses averaged over a linearly irradiated area obtained using a diffraction ring detected using an IP. Projections of residual stresses were reconstructed using the CT approach and the distribution of stress σ_x (x, y) was obtained. As long as the mean stresses were measured from the linearly irradiated area, the distribution of stress can be determined using the ordinary X-ray technique for polycrystalline aggregates by the present method without the ordinary X-ray approach for a single crystal using a four-circle goniometry.
