Bucci, 87036 Arcavacata di Rende, Italy riey@mat.unical.it Giuseppe Tomassetti Dip. di Ingegneria Civile, Università Roma "Tor Vergata", Viale Politecnico 1, 00177 Rome tomassetti@ing.uniroma2.it We consider a micropolar, linearly elastic plate-like body, clamped on its boundary and subject to a system of distance loads. We characterize, by means of Γ-convergence, the limit behavior of the solutions of the equilibrium problem when the thickness of the body vanishes. We show that, for the special case of isotropic mechanical response, the equilibrium problem described by our Γ-limit coincides with a boundary-value problem obtained in a recent deduction of a theory for shearable plates from micropolar elasticity.
