Abstract:

A computer program has been written to evaluate the effective elastic moduli of a quasi-isotropic random polycrystalline aggregate in terms of the single-crystal elastic constants. These moduli are calculated using the variational methods developed by Hashin and Shtrikman, and establish stringent limits on the upper and lower bounds for the effective elastic moduli. The program may be applied to crystals of cubic all point groups, hexagonal all point groups, trigonal point groups bar 3m, 32, and 3m and tetragonal point groups 4mmm, bar 42m, 4mm, and 422 symmetries.
