Abstract
The asymptotic values of elastic anisotropy, induced in OFHC copper by uniaxial tension and compression, are determined by a phenomenological model and compared with the predictions of Taylor type texture simulations. The evolution equation for the texture-dependent anisotropic part of the effective elasticity tensor consists of two parts. The first term depends only on inelastic rate of deformation and represents the driving term for the evolving anisotropy. The second term governs the saturation of anisotropy and is linear in the anisotropic portion of the effective elasticity tensor. In the present paper it is shown that such an evolution equation implies a reasonable prediction of the asymptotic elastic anisotropy for uniaxial tension and uniaxial compression.
