Functionally-graded materials (FGMs) are an advanced class of composite materials that exhibit continuous variations of properties, arising from spatial gradation in composition. Engineering FGM structures, thus, integrates the advantageous properties of constituent compounds. Research and development in the area of mechanics of FGMs have made great leaps towards the application of FGM structures in various engineering fields, such as aerospace, aircrafts, engine combustion chambers, fusion reactors, and biomedical devices. In addition, recent developments in material science and computational technology have enabled us to make further advancements in the research area of FGM structures, and the enthusiasm of numerous research teams is still far from being exhausted.
This Special Issue aims to collect recent studies and developments associated with mechanical problems of FGMs and FGM structures. Manuscripts are invited from various researchers/investigators, to contribute to this Special Issue with their original research articles, short communications, and review articles.

Title: Quadratic solid-shell finite elements for geometrically nonlinear analysis of functionally graded material plates.
Author: Prof. Farid ABED-MERAIM
In the current contribution, prismatic and hexahedral quadratic solid-shell (SHB) finite elements are proposed for the geometrically nonlinear analysis of thin structures made of functionally graded materials (FGM). The concept of solid-shell finite elements combines the advantages of both solid and shell formulations. The proposed SHB finite elements are formulated within a purely three-dimensional framework, with displacements as the only degrees of freedom. Also, the in-plane reduced-integration technique is used along with the assumed-strain method to alleviate various locking phenomena. Furthermore, a special direction is chosen to represent the thickness, along which an arbitrary number of integration points are arranged. These advanced finite elements can be used for the 3D modeling of thin structures with only a single element layer and few integration points in the thickness direction, which makes them very attractive due to their low computational cost. Both versions of these elements (i.e., static implicit and dynamic explicit) have been implemented into ABAQUS software in the framework of large displacements and rotations. The developed elements are coupled with functionally graded behavior for the modeling of FGM thin plates. To this end, the elastic properties of the plate are assumed to vary gradually through the thickness, according to a volume fraction power-law distribution. The performance of the resulting SHB elements is assessed through the simulation of various nonlinear benchmark problems taken from the literature. The obtained results are in good agreement with reference solutions, which reveals that the developed SHB elements represent an interesting alternative to traditional solid and shell elements for the three-dimensional modeling of FGM thin structures.
