本文导出了一个宏观各向异性应变率势，它既能描述织构金属塑性响应的各向异性，又能描述拉压不对称性。该应变率势是Cazacu等人（2006）的各向异性应力势CPB 06的精确功共轭。应用开发的应变速率势HCP高纯α-钛。
In this paper, a macroscopic anisotropic strain rate potential, which can describe both the anisotropy and tension-compression asymmetry of the plastic response of textured metals is derived. This strain rate potential is the exact work-conjugate of the anisotropic stress potential CPB06 of Cazacu et al. (2006). Application of the developed strain rate potential to HCP high-purity alpha-titanium is presented.
