2D Materials have recently attracted wide interest in the scientific community as well as in industry because their ideal mechanical and, more in general, physical performance can be drastically and sometimes unexpectedly enhanced in terms of stiffness, toughness, resilience and strength as a function of the geometry and properties of the underlying structural arrangements occurring at micro or macro levels for example in composites. The unique combination of outstanding physical, mechanical, thermal, optical and electrical properties that makes graphene the ideal candidate for next generation technology is related to its band structure and the hexagonal arrangement of the carbon atom lattice. Due to the resulting physical properties, a variety of studies have proposed potential applications of graphene in high-performance sensors, devices and composites. However, graphene represents only an example of a wide class nowadays available 2D (i.e., one-atom thick) materials, including inorganic crystalline materials, like transition-metal dichalcogenides (MoS2, MoSe2, WS2, etc.), and 2D elemental materials (silicene, germanene, and phosphorene). The unique topology found in 2D materials poses many challenges to their implementation in artificial systems, and in spite of huge efforts from the scientific community, today there is still a lack of some fundamental information about their mechanical behavior and their interaction with other materials and thus also in composites. In this symposium, we aim to discuss the main challenges related to the mechanics of 2D materials exploring the mechanical behavior of systems ranging from isolated sheets at nanoscale to nano-reinforced composite materials, to additionally investigate how nano- or micro-structures can influence adhesion, wrinkling, and mechanical and vibrational features, including stability, and auxeticity. Theoretical, numerical and experimental works are encouraged, including studies adopting a multi-disciplinary approach. Original contributions dealing with fundamental questions about the mechanics of 2D materials or reporting applications of 2D and 3D composites with microstructure or novel metamaterials are welcome.
