In this paper a second-order homogenization approach for periodic material is derived from an appropriate representation of the down-scaling that correlates the micro-displacement field to the macrodisplacement field and the macro-strain tensors involving unknown perturbation functions. These functions take into account of the effects of the...

The paper is focused on the multi-scale modeling of shear banding in two-pha se linear elastic period-ically layered strip with damaging interfaces.A two-dimensional layered strip is considered subjected to transverse shear and is assumed to have afinitethickness along the direction of the layers and an infinite extension along the direction...

New avant-garde architected materials endowed with extreme stiffness, strength and lightness may be conceived through appropriate choices of the microstructural topology, mostly aimed at optimizing the periodic distribution between the solid phases and the voids. Moreover, microstructure topologies may be designed to maximize exotic mechanical...

Mechanical metamaterials composed of a non dissipative periodic microstructure of flexible ligaments and stiff rings, viscoelastically coupled with local resonators, are considered. By following a variational approach, the linear damped dynamics are described according to a beam lattice formulation, valid for a generic coordination number. A...

This paper is concerned with the analysis of effective thermomechanical properties of multi-layered materials of interest for solid oxide fuel cells (SOFC) and lithium ions batteries fabrication. The recently developed asymptotic homogenization procedure is applied in order to express the overall thermoelastic constants of the first order...

The focus of the article is on the analysis of effective elastic properties of planar Solid Oxide Fuel Cell (SOFC) devices. An ideal periodic multi-layered composite (SOFC-like) reproducing the overall properties of multi-layer SOFC devices is defined. Adopting a non-local dynamic homogenization method, explicit expressions for overall elastic...

In this paper an asymptotic homogenization method for the analysis of composite materials with periodic microstructure in presence of thermodiffusion is described. Appropriate down-scaling relations correlating the microscopic fields to the macroscopic displacements, temperature and chemical potential are introduced. The effects of the material...

Recently, an increasing research effort has been dedicated to analyse transmission and dispersion properties of periodic metamaterials containing resonators, and to optimize the amplitude of selected acoustic band gaps between consecutive dispersion curves in the Floquet-Bloch spectrum. Potential novel applications of this research are in the...
