Connections between anisotropic tensors of thermal conductivity and thermal expansion coefficients

In this paper we derive connections between anisotropic tensors of thermal conductivity and thermal expansion coefficients of a two-phase composite and illustrate it by example of copper containing preferentially oriented graphite flakes. We model the said anisotropic tensors accounting for orientation distribution of the inhomogeneities and derive the cross-property connection by eliminating the microstructural parameters. The model is verified by comparison with the experimental data of Boden (2015) and Firkowska et al. (2015).
