摘要：

We derive relations linking the conductivity sigma* and elastic moduli of any two-dimensional, isotropic composite material. Specifically, upper and lower bounds are derived on the effective bulk modulus kappa* in terms of sigma* and on the effective shear modulus mu* in terms of sigma*. In some cases the bounds are attainable by certain microgeometries and thus optimal. Knowledge of the conductivity can yield sharp estimates of the elastic moduli (and vice versa) even for infinite phase contrast.
