Frequency and critical fluid velocity analysis of pipes reinforced with FG-CNTs conveying internal flows
M.M. Ghaitani and A. Majidian

 
Abstract
    This paper addresses vibration and instability of embedded functionally graded (FG)-carbon nanotubes (CNTs)-reinforced pipes conveying viscous fluid. The surrounding elastic medium is modeled by temperature-dependent orthotropic Pasternak medium. Flugge shell model is applied for mathematical modeling of structure. Based on energy method and Hamilton
