摘要：
In this paper, the free vibration of functionally graded carbon nanotubes reinforced composite (FG CNTRC) plates with cracks was studied. The distribution of carbon nanotubes is uniformly distributed (UD) across the plate thickness. Using Shi's third-order shear deformation theory (TSDT) and phase field theory to form the vibration equations of cracked plates. To solve these equations, the paper uses finite element method with the enrichment of finite elements around the cracked area. In computational simulation, the free vibration of FG CNTRC plates is analyzed depending on the weight ratio of CNTs, the geometrical dimensions of plate, the position, the length and the inclined angle of the cracks. The influence of different boundary conditions is also investigated. (c) 2021 Elsevier Masson SAS. All rights reserved.
