Abstract

The applicability of the counter method as an x-ray microbeam diffraction technique for measuring stresses, is discussed. Stress can be measured at local area of 330 mu in diameter for Cr powder and 450 mu for HT60 steel by using the crystal oscillation X-ray microbeam diffraction technique. The stress measured by this method agrees with the applied stress, therefore, the method is suitable for both residual and applied stresses. As an example of application, internally notched plates were stretched and stress distributions in the vicinity of notch tips were measured. The stress distributions obtained experimentally at the notch tips were similar to those calculated by the finite element method in the elastic regime. In the plastic regime, however, there was a slight discrepancy between them because of the influence of the yielding conditions of specimens.
