Static Analysis of FG-CNTRC Plates Using C0-HSDT

摘要

Recently, an edge-based smoothed discrete shear gap method (ES-DSG) based on the first-order shear deformation theory (FSDT) was developed to investigate static and free vibration analyses of Reissner-Mindlin plates [1]. In this paper, we extend ES-DSG to the CO-type higher-order shear deformation theory (CO-HSDT) to study static analysis of functionally graded carbon nanoreinforced composite (FG-CNTRC) plates. Four distributions of volume fractions of carbon nanotubes (CNTs) including UD, FG-V, FG-O, FG-X are considered. The governing equations are approximated according to a combination between ES-DSG and HSDT model. Hence, this does not require shear correction factors and improves the accuracy of the present method. Numerical examples are performed to show the reliability and accuracy of the present method.
