Reliability analysis and optimization of in-plane functionally graded CNT-reinforced composite plates

The mechanical properties of carbon nanotube/polymer composites are determined using a multi-scale approach. Starting bottom-up, the stiffness of equivalent cylinders is calculated to replace the randomly distributed carbon nanotubes in the polymer matrix. In the following, finite element simulations of the CNT/polymer composites are conducted to determine the mechanical properties of the composite. Furthermore, micromechanical homogenization techniques like Mori-Tanaka are investigated and compared with the presented approach.

“…Thus, some researchers employed numerical approaches to obtain reliable approximate two-dimensional solutions for in-plane multidirectional grada-tion in rectangular plates. Numerical solutions for non-classical boundary conditions are developed using the higher-order shear deformation theory [21][22][23] and the classical plate theories (CPT) [24][25][26][27][28][29]. Recently, Xue et al [30] reported an isogeometric numerical solution for natural frequency investigation of IPFG plates by utilizing a refined plate theory and also extended this solution to obtain a FSDT-based numerical solution for modal investigation of circular, square, and rectangular porous FGM plates having porosity gradation along the in-plane and thickness directions.…”
