Local and global instability of fluid-conveying pipes on elastic foundations
Olivier Doaré,E. de Langre +1 more
TL;DR: In this article, the relationship between the local and global bending motions of fluid-conveying pipes on an elastic foundation is investigated, and the global criterion for instability coincides with local neutrality, whereby a local harmonic forcing only generates neutral waves.

Stability analysis of multi-span viscoelastic functionally graded material pipes conveying fluid using a hybrid method

The flow-induced instability of long hanging pipes
Olivier Doaré,Emmanuel de Langre +1 more
TL;DR: In this article, the effect of increasing length on the stability of a hanging fluid-conveying pipe is investigated, and it is shown that there exists a critical length above which the flow velocity necessary to cause flutter becomes independent of the pipe length.

Dynamic stability of pipes conveying fluid
Michael P. Païdoussis,N.T. Issid +1 more
TL;DR: In this paper, the dynamics and stability of flexible pipes containing flowing fluid are examined in a general way and it is shown that conservative systems are subject not only to buckling (divergence) at sufficiently high flow velocities, but also to oscillatory instabilities (flutter) at higher flow velocity.

Die Knicklast des einseitig eingespannten, tangential gedrückten Stabes
TL;DR: In this article, the buckling load of a built-in free rod subjected to tangential end-thrust was calculated and the free vibrations underP were investigated, and it was shown that P ≥ 20,05 α/l 2 (α: flexual rigidity, l: length).
Journal ArticleDOI
Unstable oscillation of tubular cantilevers conveying fluid I. Theory
TL;DR: In this paper, a universal stability curve is constructed corresponding to conditions of neutral stability and hence separating stable and unstable regimes, by finding solutions to the equations of motion both by exact methods and also approximately by expressing the motion as the sum of the first few eigenfunctions of a cantilever beam.

Stability of a beam on an elastic foundation subjected to a follower force.
T. E. Smith,George Herrmann +1 more
TL;DR: In this article, the critical load for flutter was found independent of the foundation modulus, which characterizes the Winkler-type elastic imbedding, and the frequency of vibration of the beam increases with increasing base modulus but the magnitude of critical load is not affected.
