A new micro-macro computational strategy is proposed for the analysis of st
ructures which are described lip to the "micro" level, such as composite st
ructures. It is intended to replace standard homogenization techniques coup
led with a local reanalysis, at least for several domains of interest. This
paper describes the basis of the new approach. (C) 1999 Academie des scien
