review text: We describe a model for anisotropic material strength, and for changes in the anisotropy due to plastic strain. This model has been developed for use in high-rate, explicit, Lagrangian multidimensional continuum-mechanics codes. The model handles anisotropies in single-phase materials, in particular the anisotropies due to crystallographic texture -- preferred orientations of the single-crystal grains. We test the model by using a finite-element continuum code and a texture code specialized for hexagonal-close-packed crystal structures. The results for several uniaxial stress problems and an explosive-forming problem are shown.
