Determination of Shearing Stresses (τ_xz and τ_yz) Using X-Ray Diffraction Method with Two-Dimensional Detector

Abstract:

Measurement of shearing stresses, τ_xz and τ_yz, by X-ray diffraction technique with two-dimensional detector was studied. The principle which was developed for an area detector type X-ray triaxial stress analysis was adopted for this purpose. In the present method, Debye ring was measured first and its whole part was used for determining shearing stresses. One Debye ring is enough to determine shearing stresses without accurate diffraction data such as lattice spacing in stress free. The result of the simulation showed that the present method is useful for the evaluation of shearing stresses by X-ray diffraction technique.
