Abstract In the present work, two-phase integral theory of elasticity developed in Barretta et al. (Phys E 97:13–30, 2018) for nano-beams is generalized to model two-dimensional nano-continua. Notably, a well-posed mixture local/stress-driven nonlocal proposed accurately predict size effects Kirchhoff axisymmetric nanoplates. The key idea express elastic radial curvature as convex combination l...

• Topology optimization-based design of thermo-mechanical metadevices is proposed. The so-designed devices can be manufactured by using simple isotropic materials. performance has been analyzed via finite element method simulations. Such exhibit a good performance, when compared to more complex metadevices. present work conducted in order introduce novel approach for the mechanical conceived ma...
