“…In the case of rolling, where the orientation preservation of rolling direction (x 1 axis) direction and of rolling plane (x 1 x 2 plane) is assumed, it leads to the compensation of the following components of the grain displacement gradient tensor: and . This leads to the following grain lattice rotation, occurring after each slip shear increment δγ [4,8]:…”

“…A general relation defining the rotations appearing in deformation modeling is (see, e.g., [20]): (8) where δΩ ij is the increment of the total spin of the sample, is the increment of the plastic spin (produced by shears on active slip systems) and is the auxiliary rotation resulting from mechanical constraints imposed on the sample. Therefore:…”

“…This problem originated from the work of Hosford [1] and it was correctly defined and examined in [2,3]. It was thoroughly studied in the case of rolling deformation in the last years [4][5][6][7][8]. Let us recall an example concerning rolling process geometry.…”

“…rolling textures, i.e., brass and copper types - Fig.2. This problem was widely discussed in [6] and [8], where it was argued that deformation and textures of low stacking fault energy metals (e.g., brass, silver) are correctly described, when low values of interaction parameter (L) are used. In contrast, higher values of L should be used in the case of high stacking fault energy metals (e.g., copper).…”

Abstract. The problem of ambiguity in the definition of lattice rotation, used in plastic deformation models, is examined in this work. The geometry of tensile and compression deformation is considered. Two approaches to lattice rotation are considered: the classical definition (called also 'mathematical analysis') and the definition based on orientation preservation of specified directions/planes in the sample coordinates system. Similar study was already done by the present authors for the geometry of rolling deformation. It was shown that application of two rotation definitions enables to explain the appearance of two types of f.c.c. rolling textures: brass type and copper type textures. In the case of axisymmetric deformation the application of both definitions of lattice rotation leads to similar textures, but with different spread of their principal components.

“…In this work a simplified version of the self-consistent scheme of polycrystalline elasto-plastic deformation model, developed by Hill [22], was used. It is based on the works developed by Leffers [23] and Berveiller [24] and further strongly developed by Wierzbanowski et al [25][26][27], which is called LW model in this study. The elasto-plastic isotropic interaction between a grain and a surrounding material is expressed as: In the above definition d > 1 concerns strongly interacting slip systems, while the self-hardening corresponds to the weak one.…”

The goal of this work was theoretical and experimental study of micro-and macroscopic mechanical fields of 6061 aluminum alloy induced by the asymmetric rolling process. Two-scale constitutive law was used by implementing an elasto-plastic selfconsistent scheme into the Finite Element code (ABAQUS/Explicit). The model was applied to study the asymmetric rolling. Such a deformation process induces heterogeneous mechanical fields that were reproduced by the model thanks to the crystallographic nature of constitutive law used. The studied material was processed, at room temperature, in one rolling pass to 36% reduction. The resulting material modifications were compared with predictions of the two-scale model. Namely, the calculated textures were compared with experimental ones determined by X-ray diffraction. Especially, detailed quantitative analysis of texture variation across the sample thickness was done. The influence of this texture variation on plastic anisotropy was studied. The advantages of asymmetric rolling process over symmetric one were identified. The main benefits are a nearly homogeneous crystallographic texture, reduced rolling normal forces and homogenization of plastic anisotropy through the sample thickness.
