Abstract The composite plate problem is an eigenvalue optimization problem related to the fourth order operator ( − Δ ) 2 . In this paper we continue the study started in [10] , focusing on symmetry and rigidity issues in the case of the hinged composite plate problem, a specific situation that allows us to exploit classical techniques like the moving plane method.
