摘要：

A SELF-CONSISTENT formulation presented in a previous paper (HARREN, J. Mech. Phys. Solids 39, 345, 1991) is implemented numerically. Aggregates composed of face centered cubic crystals which deform by rate sensitive crystallographic slip are considered. Self-consistent predictions of overall stress-strain response and texture development are presented for polycrystals finitely deformed under plane strain compression and uniaxial tension. These predictions are compared to concomitant results obtained from the generalized Taylor model of ASARO and NEEDLEMAN (Acta Metall. 33, 923, 1985). Discussions concerning the numerical implementation are also included.
