Abstract
In this work, we try to answer the following question : What is the effective characteristic length of a mixture of Cosserat continua ? More generally, homogenization methods for heterogeneous Cosserat media are proposed and applied to the case of linear elasticity. They first application deals with a beam network regarded as a discrete Cosserat medium and the second with a continuous heterogeneous Cosserat continuum.
