  This paper is concerned with the analysis of effective thermomechanical
properties of multi- layered materials of interest for solid oxide fuel cells
(SOFC) and lithium ions batteries fabrication. The recently developed
asymptotic homogenization procedure is applied in order to express the overall
thermoelastic constants of the first order equivalent continuum in terms of
microfluctuations functions, and these functions are obtained by the solution
of the corresponding recursive cell problems. The effects of thermal stresses
on periodic multi-layered thermoelastic composite reproducing the
characteristics of solid oxide fuel cells (SOFC-like) are studied assuming
periodic body forces and heat sources, and the solution derived by means of the
asymptotic homogenization approach is compared with the results obtained by
finite elements analysis of the associate heterogeneous material.
