## Abstract A well‐known problem in elasticity consists in placing two linearly elastic materials (of different shear moduli) in a given plane domain Ξ©, so as to maximize the torsional rigidity of the resulting rod; moreover, the proportion of these materials is prescribed. Such a problem may not h
