Abstract
Crosslinks between the elastic moduli and electrical conductivity of two-dimensional composite materials with a variety of random microstructures are obtained with the method of finite elements. The numerical results for two-phase composites are found to be in good agreement with the approximate cross-property relations derived from the Hashin-Shtrikman (HS) bounds. For porous materials (i.e., one of the phases is void), the analytical crosslinks correlate with the numerical predictions only at relatively low porosity levels.
