Özet

In this study, the nonlinear dynamic analysis of functionally graded graphene nanoplatelet reinforced composite (FG-GPLRC) beams is examined. The material properties can be estimated by using the modified Halpin-Tsai model and rule of mixture. Based on the third-order shear deformation theory and the von Kármán assumption, the equations of motion is derived and solved by using Jacobi-Ritz method incorporating with iteration procedure. Several effects such as number of layers, weight fraction of graphene nanoplatelets, material distributions, beam geometry, velocity of moving loads, distance between the loads are considered. For nonlinear forced vibration, the results indicate a considerable dissimilarity in the nonlinear dynamic deflection of the beams under moving loads when compared to linear analysis. The incorporation of additional GPLs into the beams yields a significant improvement in the strength of the beam, resulting in lower deflection. The new findings on nonlinear response of the beams excited by one and two moving loads are presented.
