Abstract

The problem of simple extension of a multicrystalline silicon beam is discussed, by numerically analyzing the 3-D elastic fields as functions of the grain morphological and orientational portraits. These are computer-generated in accordance with assigned probability density functions. Macroscopic quantities (as centerline elongation) and the maxima of local fields (stresses, lateral boundary displacements) are correlated to distributional parameters, and are compared with those predicted by the theory of homogenization of textured polycrystals. The most significant deviations from the classic beam response are the large transverse displacements, and the moderate cross-sectional stresses, associated with certain microdistributions. The numerical analysis is performed with the software ABAQUS on a DEC 5000 workstation.
