Non-uniform Deformation of Polycrystalline
The thinning processing of crystal grain boundary lines and calculation of strain of crystal grains are programmed for estimation of the non-uniform deformation behavior of crystal grains in polycrystalline material. The thinning processing of crystal grain boundary line is calculated by image processing based on Hilditch method. Logarithmic strains are calculated by measuring maximum distances of grain boundaries of respective grains at every degree interval from the loading direction. The strain distribution in all direction for a grain is approximated with an ellipse using the method of least squares and the principal strain are obtained as the long and the short axes of the ellipse. The calculation accuracy of these programs is examined in detailed.
