Abstract
A method for bounding the overall strain-rate potential of polycrystalline materials will be presented. The formulation contains one or two points of subtlety but the resulting optimization problem is straightforward and can be solved equally easily for any pattern of prescribed loading, and for polycrystals with any texture, giving rise to anisotropic material response. Sample results will be presented for f.c.c. polycrystals, textured so as to display overall transversely isotropic material response, but subjected to general loads that do not respect this symmetry.
