摘要：

A Monte Carlo finite element model is developed for predicting the scatter in the nominal elastic constants of a thin film aggregate of cubic crystals. Universal results for the nominal plane strain Young's modulus and Poisson's ratio are presented as functions of the number of grains within a unit volume, acid two parameters that quantify the level of the crystalline anisotropy. The predictions are compared with formulae that are derived for plane strain Voigt and Reuss bounds. (C) 1997 Acta Metallurgica Inc.
