Energy from renewable resources is central to environmental sustainability. Among the
renewables, sunlight-driven fuel synthesis is a sustainable and economical approach to …

In this paper, we give a review of the state of the art in the study of mechanical
metamaterials. The very attractive property of having a microstructure capable of …

Recent advancements in manufacturing, finite element analysis (FEA), and optimization
techniques have expanded the design possibilities for metamaterials, including isotropic …

The lattice structure is a type of cellular material with trusslike frames which can be
optimized for specific loading conditions. The fabrication of its intricate architecture is …

In this paper, we account for the research efforts that have been started, for some among us,
already since 2003, and aimed to the design of a class of exotic architectured, optimized …

In the last decade, the exotic properties of pantographic metamaterials have been
investigated and different mathematical models (both discrete or continuous) have been …

Multilayer pantographic metamaterials, in short, pantographic blocks, have shown peculiar
mechanical behavior, especially when their constitutive hinges are revolving (ie, perfect) …

The global response of experimental uniaxial tests cannot be homogeneous, because of the
unavoidable presence of localized deformations, which is always preferential from an …

Hencky (Über die angenäherte Lösung von Stabilitätsproblemen im Raum mittels der
elastischen Gelenkkette. Ph. D. thesis, Engelmann, 1921) proposed a discrete model for …

We determine the effective behavior of periodic structures made of welded elastic bars.
Taking into account the fact that flexural and torsional stiffnesses are much smaller than the …
