摘要

The "variational" homogenization method developed by deBotton and Ponte Castaneda is used here to predict texture development in halite polycrystals at room and high temperatures accounting for hardening and grain shape changes. The new predictions are compared with those of the Taylor and "tangent" model of Molinari et al. for uniaxial tension and compression. The predictions of the "variational" model are found to be intermediate between the Taylor and "tangent" predictions, although not too different from either, as a consequence of the relatively high isotropy of the halite single crystal grains.
