The random generated initial distributions of (a) (111) equal area pole figure and (b) bicrystal interface normals represent the initially isotropic texture for undeformed OFHC copper. Axis perpendicular to the projection plane is the loading direction in uniaxial tension/compression or plane strain compression.

The calculated equivalent macroscopic stress, σ̄eq, as a function of equivalent macroscopic strain, ε̄eq=∫ot33dt, in uniaxial compression test for (a) pure Sachs model, (b) Sachs-bicrystal model, and (c) Taylor-bicrystal model of the same given material constants
Grahic Jump Location
The predicted crystallographic textures obtained from (a) pure Sachs model, (b) Sachs-bicrystal model, and (c) Taylor-bicrystal model under uniaxial compression for ε̄eq=0.5. Axis perpendicular to the projection plane is the loading direction.

Grahic Jump Location
The predicted textures obtained from (a) pure Sachs model, (b) Sachs-bicrystal model, and (c) Taylor-bicrystal model for ε̄eq=0.6 in uniaxial tension test. Axis perpendicular to the projection plane is the loading direction.
Grahic Jump Location
The predicted σ̄eq vs. ε̄eq curves for constant strain-rate plane strain compression test (with D̄eq/γ̇o=1) obtained by (a) pure Sachs model, (b) Sachs-bicrystal model and (c) Taylor-bicrystal model
Grahic Jump Location
Texture evolution are shown by pole figures for ε̄eq=0.5 under plane strain compression test obtained by (a) pure Sachs model, (b) Sachs-bicrystal model, and (c) Taylor-bicrystal model. Axis perpendicular to the projection plane is the loading direction, and the flow direction is at the top of the pole figure.
