“…Since the trends are to improve product quality, more accurate simulations of the manufacturing processes and of the products in service are needed. In these numerical solutions, anisotropy of the metals plays an important role [1][2][3][4][5][6][7][8][9].…”

“…[22] However, it is shown in some cases that even in nonstable monocrystals, in which orientation changes during deformation, the coefficient R remains constant during straining. [27] Thus, the correlation between coefficient R and texture is not so obvious. In the case of AA8011 specimens, these results are consistent with those reported for aluminum sheets by Kleemola and Fig.…”

The effects of gage length, width measurement locations, and specimen geometry on plastic strain ratio have been investigated for the AA8011 aluminum alloy and interstitial-free (IF) steel sheets. The specimens were ASTM E 517 to 92a subsize, type A, and type A alternative with, respectively, 37.5, 76, and 57 mm reduced parallel sections and with different fillet radii. In each specimen type, there were differences in axial strains of gage marks and changes in width strain over the reduced parallel section, which depend on the applied axial strain, reduced parallel section length, and fillet radius. Therefore, the magnitudes of the calculated R-values depend upon gage length, width measurement location, axial strain, and specimen geometry. These dependencies were more pronounced in the high R-value IF steel sheet relative to the low R-value AA8011 aluminum alloy sheet. The dependencies of R-value on gage length and width measurement location are negligible in all AA8011 specimens, while in IF specimens, these dependencies can be neglected only for type A specimens with 12.5-mm fillet radius. It is concluded that the observed differences in the measured R-values for specimens with different geometries can be attributed to the constraints imposed by the shoulders, which affect the width strain measurements and the resulting R-values.

“…12C). By the reaction with Me 2 SO 4 and LAH, these charge defects convert to electro-inactive sp 3 carbons. The density of reactant sites is very low (less than one thiopene unit in 10 4 -10 5 ), and therefore, the treatment does not change the material chemically, but nevertheless, the optoelectronic properties significantly change.…”

“…As an example, almost defect-free metallic single crystals have weaker mechanical properties than polycrystalline ones, since in the latter the interaction between defects and grain boundaries are strong. 3,4 Control over these defects and their associated nanostructural heterogeneity, known as defect engineering, [5][6][7][8] therefore is an approach that permits material properties to be tailored for functional devices such as semiconductors, paramagnets, thermoelectrics, and ferroelectrics. [9][10][11][12][13] In hard solids, defects are divided into four classes according to their dimension: point, line, planar, and volume defects, 14,15 as shown in Fig.…”
