The M&MoCS workshop “Microstructures and Microarchitectures: Theoretical, Numerical, Experimental Aspects” aims at gathering scientists from various fields around the physics, mechanics, and mathematics of solids and structures. In particular, the workshop targets at combining the expertise of theoretical, computational and experimental research activities for the development of physico-mathematical models and methods for the design and analysis of the materials, metamaterials and complex structures of today and the future.

Material microstructures – typically observable at micro- or nano-scales – play an essential role in the classical engineering materials such as metals and concrete as well as in the development of new materials and composites. Analogously at larger scales, spatial configurations, topologies, or architectures – together with structural dimensions – determine the robustness of many classical engineering structures such as trusses, cellular lattices or sandwich structures. These two worlds meet, at various scales, in the modern materials and composite design as well as in the development of mechanical metamaterials.

Modern manufacturing technologies such as additive manufacturing have shown to provide an optimal way to realize novel metamaterials characterized by complex microstructures. Mechanical behavior tailored for specific purposes seems to be already technologically possible and soon easily usable in industrial applications.

The available theoretical models and analysis of mechanics need to be improved and adapted to the new challenges presented by the need of conceiving and designing new metamaterials. Discrete Lagrangian models, their dissipative counterparts, generalized continuum models are all useful conceptual tools which may be of use in predicting the mechanical behavior of exotic microstructures and microarchitectures.

Classical and modern computational analysis methods, ranging from standard finite elements to, e.g., isogeometric analysis techniques, naturally play a fundamental role in the design and understanding of these structures.

The recent developments in the experimental research, such as digital image correlation, supplies a further tool for the development of technological solutions: the predicted nonstandard behavior of designed microstructures can be verified with quantitative precision never achieved before.
