Modeling and analysis of functionally graded carbon nanotube reinforced composite structures: A review

Functionally graded carbon nanotube reinforced composite (FG-CNTRC) is a new generation of advanced composite materials, where carbon nanotubes (CNTs) are used as the reinforcements in a functionally graded pattern. The mechanical behavior of FG-CNTRC has emerged as one of the recent hot research topics in materials science and engineering. This paper presents a review of the developments in the modeling and analysis of FG-CNTRC structures. The emphasis are put on the linear and nonlinear bending, buckling and postbuckling, and free and forced vibration of FG-CNTRC beams, plates, shells and shell panels under various loading, boundary and environmental conditions. The presented progresses lay foundation for future studies in the area of FG-CNTRC structures. Some critical aspects for further explorations are highlighted.
