Since it is generally impossible to determine exactly the effective properties of random heterogeneous media, any rigorous statements about effective properties must take the form of bounds. In Chapter 14 we formulated variational (extremum) principles for the effective properties that are given in terms of trial fields. Here we will derive specific existing bounds on the effective conductivity, effective elastic moduli, trapping constant, and fluid permeability by constructing specific trial fields that conform with the variational principles.
