Hot fluid induced temperature-dependent vibration and instability of embedded FG-CNTRC Reddy pipes

In this paper, nonlinear vibration and instability of embedded nano-composite temperature-dependent polymeric pipes conveying hot viscous fluid are investigated. The pipe is reinforced by Single-Walled Carbon NanoTubes (SWCNTs) with Uniform Distribution (UD) and three types of Functionally Graded (FG) distribution patterns. The FG-carbon nanotube reinforced composite (FG-CNTRC) pipe is located in an orthotropic temperature-dependent visco-elastomeric medium. Reddy higher-order shear deformation theory is employed to establish the governing equations. The frequency and critical fluid velocity of the structure are calculated using Differential Quadrature Method (DQM). The effects of different parameters on the nonlinear vibration and instability of the pipe are investigated.
