%X We have calculated the strain energy densities for various grain orientations for a fcc polycrystalline film on a substrate. The results show that, prior to yielding, the five lowest strain energy densities correspond to the grains with (100), (510), (410), (511) and (310) planes oriented parallel to the film surface. In an yielded film, the five lowest strain energy densities correspond to the grains with (110), (100), (511), (411) and (211) planes oriented parallel to the film surface. Considering strain energy only, we predicate that the grains with these orientations should be favorable in crystal growth successively.
