The influence of cylindrical geometry on X-ray stress tensor analysis. I. General formulation.
Abstract : Stress analysis by X-ray diffraction, usually performed on a specimen with plane geometry, becomes very dificult on more complex surfaces. A model is proposed to calculate the six independent components of the stress tensor cylindrical symmetry. The mathematical approach described highlights two distinct effects that modify values of measured strain by X-ray diffraction, a rotation effect and a translation effect. The X-ray absorption by the material is taken into consideration and two models are proposed to undertake the mathemetical processing on thick materials and thin layers. It is equally possible to take into account, for example, crystallographic texture and experimental features as (psi phi) oscillations. Examples and applications will be given in paper II.
