Polycrystalline materials comprised of grains obtained froma
single anisotropic material are considered in the frameworkof
linear elasticity. No assumptions on the symmetry of
thepolycrystal are made. We subject the material to
independentexternal strain and stress fields with prescribed mean
values.We show that the extremal overall elastic response is
alwaysachieved by a configuration consisting of a single
properlyoriented crystal. This result is compared to results for
isotropicpolycrystals.
