Stability Optimization of Functionally Graded Pipes Conveying Fluid
This paper presents an exact analytical model for optimizing stability of thin-walled, composite, functionally graded pipes conveying fluid. The critical flow velocity at which divergence occurs is maximized for a specified total structural mass in order to ensure the economic feasibility of the attained optimum designs. The composition of the material of construction is optimized by defining t...

متن کاملAnalysis of the Effect of Fluid Velocity on the Instability of Concrete Pipes Reinforced with Nanoparticles Conveying the Fluid Flow
With respect to the great application of pipes conveying fluid in civil engineering, presenting a mathematical model for their stability analysis is essential. For this purpose, a concrete pipe, reinforced by iron oxide (Fe2O3) nanoparticles, conveying fluid is considered. The goal of this study is to investigate the structural stability to show the effects of the inside fluid and the nanopart...
متن کاملStability Issues of Concentric Pipes Conveying Steady and Pulsatile Fluids
In this paper, we study both the static and dynamic stabilities of submerged and inclined concentric pipes conveying uid. The governing equation for the inner tubular beam is derived under small deformation assumptions. We obtain the dis-cretized dynamical equations using spatial nite diierence schemes. In the case of steady ow, both buckling and utter instabilities are investigated. In the cas...
متن کاملOn stability of a clamped-pinned pipe conveying fluid
In the past, stability of an undamped clamped-pinned pipe conveying fluid has been always considered numerically leading to controversial results. Païdoussis (2004) has shown that a numerical stability analysis of a clamped-pinned pipe requires exceptionally large number of vibration modes to obtain the correct dynamical behaviour. In this paper, analytical proof of stability of a clamped-pinne...
