The worst possible mechanical performance of a composite material of given composition is attained for a homogeneous distribution of the second phase. This conclusion is reached upon analyzing the St. Venant problem (extension, torsion, bending, flexure) for a wide class of FGMs in this communication. With opportunities for optimization in full view, the problem of FGM optimization is then addressed, in the context of the thermoelastic response of bi-phase, anisotropic layers.
