Hashin-shtrikman upper bound

WebDec 1, 2008 · The choice f = 0 results in the upper Hashin-Shtrikman bound, while f = 1 gives the lower Hashin-Shtrikman bound. All intermediate structures are within these bounds, and can be obtained by varying f from 0 to 1. The limiting cases are the ones we present in our figures.
