Many models for the structural analysis of advanced structures AS (metallic, layered, sandwich, laminated composites, smart with piezo layers, bio-structures, etc.) in multiphysics environment ME (mechanical, thermal, electrical, magnetic, etc.) are defined in degenerated threedimensional 3D domains, involving plate, shell and beam geometries. Nowadays, available FE commercial codes incorporate most of the acquired knowledge on beam/plate/shell element formulations, and they can be considered to be a robust and effective analysis tool for many of the applications of engineering interest. However, a number of new topics are emerging in the AM and ME analysis, these are currently under investigation in computational structural mechanics, which require new tools. New ideas from the theory of structures point of view as well as new discretization strategies able to circumvent or at least alleviate the drawbacks related to mesh-based discretizations of fully 3D models defined in reduced plate/shell/beam domains are elerging. The present topical issue aimsto collect contribution on these new methodology.
