Nonlinear dynamics of extensible fluid-conveying pipes, supported at both ends
TL;DR: In this paper, the post-divergence behavior of extensible fluid-conveying pipes supported at both ends is studied using the weakly nonlinear equations of motion of Semler, Li and Paidoussis.

Three-dimensional dynamics of a fluid-conveying cantilevered pipe fitted with an additional spring-support and an end-mass
TL;DR: In this article, the authors examined how the dynamics of a cantilevered pipe with additional spring-support is modified by the presence of a small mass attached at the free end.

Flutter of long flexible cylinders in axial flow
TL;DR: In this article, the stability of a thin flexible cylinder considered as a beam, when subjected to axial flow and fixed at the upstream end only, is analyzed using a finite-difference scheme in space to the equation of motion expressed in the frequency domain.
Chaotic response is a generic feature of vortex-induced vibrations of flexible risers

TL;DR: In this article, the authors show that the vortex-induced vibrations of long flexible risers are characterized by time intervals of chaotic response, followed or preceded by periods of statistically stationary response.

Vortex-induced vibration and galloping of prisms with triangular cross-sections
TL;DR: In this paper, a flexible mounted triangular prism allowed to oscillate in the cross-flow direction is studied experimentally, covering the entire range of possible angles of attack, and the frequency of oscillations locks into the natural frequency twice: once approaching from the Strouhal frequencies and once from half the strouhal frequency.
