Asymptotic behaviour of micropolar adhesives

This work describes the asymptotic mechanical behaviour of two elastic adhe rends adhesively bonded by a thin elastic micropolar adhesive when the thin ness of the adhesive layer goes to 0. This asymptotic analysis is performed using first the asymptotic expansion method through the mixed Hellinger-Re issner variational formulation. Then we use an epi-convergence argument, th rough the definition of an energy functional associated to the problem. Fin ally the case of two elastic micropolar adherends adhesively joined by a th in micropolar adhesive is studied.
