Asymptotic modelling of heat conduction in a particulate composite with imperfect contact between the components

The paper outlines an approach to the analysis of periodically inhomogeneous composites with imperfect contact between the components. The heat-conduction problem for a particulate composite with an infinite matrix and simple cubic lattices of spherical inclusions is solved. Approximate solutions for the effective heat-conductivity coefficient and local heat fluxes at the microlevel are found. The results are obtained for arbitrary conductivity and volume fractions of the components
