Abstract
Porous composites with several media are an attractive material system for multi-functional composite materials. Thermal conductive and thermoelastic properties are analyzed by mean of macro and microscopic treatments. For efficient numerical calculation, micromechanics model of the porous composite is proposed for predicting the behavior of a material. A periodical microstructure of the composite is assumed and a homogenization theory is applied with asymptotic expansion of temperature and displacement fields. Random distribution of voids and particle is generated in the periodical unit cell region and the effective conductive and thermoelastic properties are evaluated.
