An important target in industry is that of developing new technologies for microelectromechanical systems (MEMS) and nanoelectromechanical systems (NEMS), designed for a multitude of applications in many technical fields. For example, carbon nanotubes are currently considered very prominent materials owing to their excellent electric, thermal, and mechanical properties. These new materials are employed also for purely mechanical purposes. In fact, carbon nanotubes are often used as reinforcement of traditional construction materials, because their application can improve significantly the tensile strength.

Micro-, meso-, and nanostructures need a structural and constitutive modeling consistent with their actual geometrical dimensions. In this regard, it is necessary to develop suitable models that lead to reliable results, since in the literature they are often not available. This special issue is dedicated to theoretical, numerical, and experimental investigations of the behavior of structures at micro-, meso-, and nanoscale. The purpose is to collect and compare the contributions of a research topic very timely and of great scientific interest.

Potential topics include, but are not limited to:

• Static analysis, buckling, and vibration of micro-, meso-, and nanostructures
• Nanobeams, nanoshell, and nanoplates
• Micro-, meso-, and nanostructural effects
• Size effects
• Microelectromechanical systems (MEMS)
• Nanoelectromechanical systems (NEMS)
• Nonlocal theory applied to micro-, meso-, and nanoscales
• Nanocomposite materials
• Carbon nanotubes
• Micro- and mesomechanics of concrete
• Functionally graded materials
• Piezo and magnetic elastic materials
• Homogenization techniques
