Solution methods for the growth of a repeating imperfection in the line of a strut on a nonlinear foundation
Romain Lagrange, Daniel Averbuch
This paper is a theoretical and numerical study of the uniform growth of a repeating sinusoidal imperfection in the line of a strut on a nonlinear elastic Winkler type foundation.…
Limit point buckling of a finite beam on a nonlinear foundation
Romain Lagrange
In this paper, we consider an imperfect finite beam lying on a nonlinear foundation, whose dimensionless stiffness is reduced from to as the beam deflection increases. Peri…
Compression-induced stiffness in the buckling of a one fiber composite
Romain Lagrange
We study the buckling of a one fiber composite whose matrix stiffness is slightly dependent on the compressive force. We show that the equilibrium curves of the system exhibit a li…
Fluid-elastic coefficients in single phase cross flow: dimensional analysis, direct and indirect experimental methods
Romain Lagrange, Philippe Piteau, Xavier Delaune +1
The importance of fluid-elastic forces in tube bundle vibrations can hardly be over-emphasized, in view of their damaging potential. In the last decades, advanced models for repres…
New estimations of the added mass and damping of two cylinders vibrating in a viscous fluid, from theoretical and numerical approaches
Romain Lagrange, Yann Fraigneau
This paper deals with the small oscillations of two circular cylinders immersed in a viscous stagnant fluid. A new theoretical approach based on an Helmholtz expansion and a bipola…
FSI -- Vibrations of immersed cylinders. Simulations with the engineering open-source code TrioCFD. Test cases and experimental comparisons
Domenico Panunzio, Maria Adela Puscas, Romain Lagrange
In this paper, we assess the capabilities of the Arbitrary Lagrangian-Eulerian method implemented in the open-source code TrioCFD to tackle down two fluid-structure interaction pro…
