Stress-orientation distribution function (SODF) - Description, symmetry and determination
2000 (English)In: Materials Science Forum, ISSN 0255-5476, Vol. 347-3, 66-71 p.Article in journal (Refereed) Published
In this paper, a stress-orientation distribution function (SODF) is defined to describe statistically the distribution of the stress state of grains as a function of crystal orientation. Similar to the crystal orientation distribution function (CODF), the SODF may be expressed as generalized spherical harmonics. The two symmetry groups existing in the SODF, namely the crystal symmetry and the sample symmetry, are discussed. A method to construct the SODF directly from neutron or X-ray diffraction data is described, Finally, the validity of the method is demonstrated by stress analysis of simulated strain distributions in an austenitic stainless steel under tensile loading.
