Verification of the prediction of deformation-induced anisotropy for simple deformation modes: uniaxial state and pure shear state of stress

Abstract

Deformation texture with preferred orientation is developed by external disturbance applied to the grain during the deformation process such as rolling. The formation of deformation texture is strongly influencing the mechanical property of the product, and material anisotropy is observed from the deformation texture, macroscopically. Therefore, the proper consideration and analysis of deformation texture is required. In the present work, the method for prediction of deformation-induced anisotropy employing the phenomenological yield potential is proposed. The proposed algorithm is applied to the anisotropic evolution for simple deformation modes, such as uniaxial stress state and pure shear stress state in X-Y direction. In order to verify the effectiveness of the method, the result from the proposed algorithm is then compared with that from the crystallographic texture analysis. (C) 2003 Elsevier Science B.V.
