Effective thermoelastic properties of composites with temperature-dependent constituents

Effective thermoelastic properties—elasticities, thermal expansions, heat capacities—of composites with temperature-dependent constituents are derived all at the same time using a unified thermodynamic treatment within Kovalenko’s thermoelasticity theory, which assumes the strain to be small but places no restrictions on temperature variations. Known results on elasticities and thermal expansions are rederived in a new way and new results on thermal expansions and heat capacities are obtained. In addition, the temperature-independent framework is revisited and expressions for the effective properties are obtained that are free of the restrictions placed on temperature variations within linear thermoelasticity.
