Nonlinear static analysis of CNT/nanoclay particles reinforced polymer matrix composite plate using secant function based shear deformation theory

ABSTRACT The mechanically induced nonlinear statical assessment of the bending response of single-walled carbon nanotubes (CNTs) fibers on nanoclay-particle-reinforced polymer hybrid laminated composite plate is explored under static loading conditions. A numerical approach is used to find the mechanical properties of CNT-reinforced hybrid laminated plates prepared by involving nanoclay particles in the existing CNT-reinforced epoxy composites. The transverse nonlinear central deflection of a hybrid nanocomposite subjected to mechanical loading based on the Halpin–Tsai approach is evaluated. For the fundamental formulation, a secant-function-based shear deformation theory (SFSDT) and von Kármán nonlinearity are implemented. The influence of CNT/nanoclay particles over the nonlinear bending responses of the hybrid laminated plate under various loading circumstances is studied in detail. A Newton–Raphson method based on nonlinear finite element technique is used for the hybrid nanocomposite plate. Furthermore, the impact of different design parameters, such as thicknesses of CNT fibers, different interphases along with aspect ratios, stacking sequences under different boundary conditions, and the types of loads on the nonlinear transverse central deflection of CNT/nanoclay-reinforced polymer hybrid composite plate, has been investigated. The effectiveness of the suggested model has been confirmed by comparing it to deflection reactions found in the literature. Graphical abstract
