Abstract
A Monte Carlo finite element model is developed for predicting the sca tter in the nominal elastic constants of a thin film aggregate of cubi c crystals. Universal results for the nominal plane strain Young's mod ulus and Poisson's ratio are presented as functions of the number of g rains within a unit volume, acid two parameters that quantify the leve l of the crystalline anisotropy. The predictions are compared with for mulae that are derived for plane strain Voigt and Reuss bounds. (C) 19 97 Acta Metallurgica Inc.
